CVE-2026-56443: CWE-863 in Gitea Gitea Open Source Git Server
Token public-only scope bypassed on Limited-visibility owners (Repository + Package categories) — residual after CVE-2026-25714 / PR #37118
AI Analysis
Technical Summary
Gitea before version 1.27.0 contains a vulnerability (CVE-2026-56443) where the 'public-only' personal access token scope can be bypassed for repositories and packages owned by users with 'Limited' visibility. The visibility checks for these categories mistakenly treat 'Limited' visibility as non-private, enabling tokens scoped for public-only access to read internal content. This affects API endpoints for packages, repositories, and web download routes. The flaw was verified in version 1.26.2 and represents a residual issue after a previous fix (CVE-2026-25714).
Potential Impact
An attacker with a personal access token limited to 'public-only' scope can gain unauthorized read access to repositories and packages that are intended to be restricted under 'Limited' visibility. This exposure affects internal content that should not be accessible to such tokens, potentially leaking sensitive information. The vulnerability does not allow modification or denial of service, only unauthorized read access.
Mitigation Recommendations
A patch is available that fixes this visibility check issue in Gitea version 1.27.0. Users should upgrade to version 1.27.0 or later to remediate this vulnerability. Since this is not a cloud service, remediation depends on applying the official fix. No other mitigation steps are indicated by the vendor advisory.
