  "details": "## Summary\nCVE-2026-20800 fixed private-info leakage to revoked users only for the notification endpoint. Two\nsibling endpoints that return data keyed on the caller\u0027s own relationship still do not re-check repo\naccess at output time:\n- `GET /api/v1/user/starred` \u2014 `getStarredRepos()` computes a per-repo permission but still lists every\n  starred repo (no filtering), so the full repo object (`full_name`, `private`, `clone_url`, `ssh_url`)\n  of a now-inaccessible private repo is returned.\n- `GET /api/v1/user/times` \u2014 `ListMyTrackedTimes()` queries by `UserID` only and `LoadAttributes` brings\n  in the issue (`title`, `state`), leaking private issue titles after revocation.\n\n## Steps to reproduce\nUsing the provided reproduction materials, as a revoked user:\n1. Control: `GET /api/v1/repos/admin/starred-test` \u2192 **404**.\n2. `GET /api/v1/user/starred` \u2192 leaks `admin/starred-test`, `private:true`, `clone_url`.\n3. `GET /api/v1/user/times` \u2192 leaks `issue.title = \"SECRET: \u2026\"`, `state`.\n\n(Runtime-confirmed on `gitea/gitea:1.25.4`. Oracle = planted sentinel title; no real secret exfiltrated.)\n\n## Impact\nA former collaborator can enumerate private repos they starred and read private issue titles they logged\ntime on, indefinitely after access revocation. Metadata only (no repo content / comment bodies). Low.\n\n## Suggested remediation\n1. `getStarredRepos`: drop (or minimally redact) repos where `permission.HasAnyUnitAccessOrPublicAccess()`\n   is false for the caller.\n2. `ListMyTrackedTimes`: filter tracked-time entries by current repo access.\n3. Optionally clear a user\u0027s stars / time entries for a private repo on revocation.\n\n## Credit\nReported as part of an incomplete-patch measurement study (responsible disclosure).",
