Two\nsibling endpoints that return data keyed on the caller's own relationship still do not re-check repo\naccess at output time:\n- `GET /api/v1/user/starred` — `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` — `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` → **404**.\n2. `GET /api/v1/user/starred` → leaks `admin/starred-test`, `private:true`, `clone_url`.\n3. `GET /api/v1/user/times` → leaks `issue.title = \"SECRET: …\"`, `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's stars / time entries for a private repo on revocation.\n\n## Credit\nReported as part of an incomplete-patch measurement study (responsible disclosure).","state":0,"publishedAt":"2026-07-21T20:13:03+00:00","modifiedAt":"2026-07-27T17:11:25.8898035+00:00","affected":[{"ecosystem":"Go","name":"code.gitea.io/gitea","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.27.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-qf2f-qh6p-7v89","https://github.com/go-gitea/gitea","https://github.com/go-gitea/gitea/releases/tag/v1.27.0"],"sourceUrl":"https://github.com/advisories/GHSA-qf2f-qh6p-7v89","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-qf2f-qh6p-7v89","identifiers":["GHSA-qf2f-qh6p-7v89","CVE-2026-59766","GO-2026-6071"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
