Description

Coder from 2.0.0 before 2.34.8 contains an incorrect authorization vulnerability in the acl_allow rule of coderd/rbac/policy.rego, which does not verify organization membership for per-user ACL entries, and organization member removal does not scrub those entries. Authenticated users removed from an organization can keep accessing previously granted org-scoped resources such as templates and workspaces via the API.
