CVE-2026-58437: CWE-284 in Gitea Gitea Open Source Git Server
Repository Visibility Manipulation via Git Push Options
AI Analysis
Technical Summary
CVE-2026-58437 is a vulnerability in Gitea (code.gitea.io/gitea) affecting versions before 1.27.0. It allows users with owner or admin collaborator privileges to change repository visibility and template status through undocumented git push options. These modifications bypass standard monitoring mechanisms such as audit logs, webhook events, notifications, permission recalculations, and timestamp updates, which can be exploited to make stealthy changes including temporarily exposing private repositories or silently altering template repositories.
Potential Impact
The vulnerability enables privileged users to make stealthy changes to repository visibility and template status without triggering audit logs or notifications. This can result in temporary exposure of private repositories or undetected modifications to template repositories, potentially compromising confidentiality and trust in repository management.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade Gitea to version 1.27.0 or later to remediate this issue. Since this is not a cloud service, remediation depends on applying the official fix.
