Executive Summary

CVE-2026-58433 is a broken access control flaw in Gitea affecting versions up to 1.26.4. It allows a team member with repository admin rights to bypass the RepoAdminChangeTeamAccess setting and grant their entire team access to a repository via the PUT /api/v1/teams/{id}/repos/{owner}/{repo} endpoint. This setting is meant to prevent non-owners from linking teams to repositories.

Detection Guidance

Check Gitea logs for suspicious API calls to PUT /api/v1/teams/{id}/repos/{owner}/{repo} or PUT /api/v1/repos/{owner}/{repo}/teams/{team} that grant team access without proper authorization. Review repository access logs for unauthorized team additions.

Impact Analysis

This vulnerability enables privilege escalation where a non-owner with repo admin rights can silently grant access to an entire team, potentially exposing private repository data to unintended users. It also affects the RemoveTeamRepository endpoint, further compromising repository access controls.

Mitigation Strategies

Upgrade Gitea to a patched version beyond 1.26.4. Temporarily disable the vulnerable endpoints if an upgrade is not immediately possible. Review and audit all team repository access permissions for unauthorized changes.
