GHSA-qf2f-qh6p-7v89 — Gitea CVE-2026-20800 sibling endpoints not covered: revoked user still reads private repo objects via `/api/v1/user/sta…

Affected: Go: code.gitea.io/gitea

## Summary CVE-2026-20800 fixed private-info leakage to revoked users only for the notification endpoint. Two sibling endpoints that return data keyed on the caller's own relationship still do not re-check repo access at output time: - `GET /api/v1/user/starred` — `getStarredRepos()` computes a per-repo permission but still lists every starred repo (no filtering), so the full repo object (`full_name`, `private`, `clone_url`, `ssh_url`) of a now-inaccessible private repo is returned. - `GET /api/v1/user/times` — `ListMyTrackedTimes()` queries by `UserID` only and `LoadAttributes` brings in the issue (`title`, `state`), leaking private issue titles after revocation.

## Steps to reproduce Using the provided reproduction materials, as a revoked user: 1. Control: `GET /api/v1/repos/admin/starred-test` → **404**. 2. `GET /api/v1/user/starred` → leaks `admin/starred-test`, `private:true`, `clone_url`. 3. `GET /api/v1/user/times` → leaks `issue.title = "SECRET: …"`, `state`.

(Runtime-confirmed on `gitea/gitea:1.25.4`. Oracle = planted sentinel title; no real secret exfiltrated.)

## Impact A former collaborator can enumerate private repos they starred and read private issue titles they logged time on, indefinitely after access revocation. Metadata only (no repo content / comment bodies). Low.

## Suggested remediation 1. `getStarredRepos`: drop (or minimally redact) repos where `permission.HasAnyUnitAccessOrPublicAccess()` is false for the caller. 2. `ListMyTrackedTimes`:…
