What is CVE-2026-52813?
CVE-2026-52813 is a critical path traversal vulnerability in gogs, published on 24 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Gogs is an open source self-hosted Git service. Prior to 0.14.3, organization names containing path traversal sequences (../) are accepted by Gogs, and repositories under them are written to paths following these path traversals. This allows storing/retrieving data for repositories at arbitrary locations on the filesystem. By creating nested structure of Git repositories, one can overwrite the other's hooks configuration to result in Remote Code Execution (RCE). This vulnerability is fixed in 0.14.3.
Weakness: CWE-23
