AI-suggested

Upgrade Gitea to version 28.4.0 or later, where the issue is fixed. The fix changes the pattern matching to use unquoted file names and properly reports renames, restoring the intended protection mechanism. No other mitigation is required once upgraded.

Description

CVE-2026-123638 is a protection mechanism failure in Gitea affecting versions before 28.4.0. The issue arises because the 'Protected file patterns' setting was matched against git-quoted file names, causing files with special characters to bypass protection. This allowed users with write access to modify or rename protected files, potentially adding malicious workflows that execute on repository runners. The flaw is fixed in version 28.4.0 by changing the pattern matching to use unquoted file names and reporting renames with both old and new paths.
