Summary
Gogs is an open source self-hosted Git service. Prior to 0.14.0, as an authorized user, an intruder can dictate the value which is passed to the git diff command which, together with bypassing the filtering of the passed value, allows the user to bypass the target directory and write the result of the comparison to any arbitrary path. This vulnerability is fixed in 0.14.0.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
