Prior to 5.2.3, the shared project permission check trusted a caller-controlled team_id and let the teamOwner/teamAdmin branch continue without confirming that the target project belonged to that team. The vulnerable surface is project routes and related authorization checks that accepted user-controlled project identifiers. An authenticated user who is an owner or admin of their own team submits a victim project id together with the attacker's own team_id in the request body; default self-signup grants the required role on the user's own team. Authorization is evaluated against the attacker-selected team instead of the target project's team, and the update path mass-assigns the request body without a project field allow-list. The attacker needs a valid Chartbrew account, an owner or admin role on their own team, and a victim project identifier; requests without the body team_id trick are rejected. The attacker can re-parent the victim project into their own team, gain full read and write access, expose it publicly, remove password protection, and cause the victim to lose it; the shared delete route also permits cross-tenant deletion. This issue is fixed in version 5.2.3."}], "source": {"advisory": "GHSA-6gv3-8wxh-6vfq", "discovery": "UNKNOWN"}}}}
