CVE-2026-58420: Gitea: Local File Inclusion via file:// URI in Migration Restore

July 21, 2026

Gitea’s restore-repo command processes release.yml files from a user-supplied archive. The DownloadURL field in each release attachment is passed to uri.Open() without scheme validation. Because uri.Open() supports the file:// scheme via os.Open(), an operator-level attacker can plant a crafted release.yml to exfiltrate arbitrary files from the server filesystem as release attachments.
