Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Gogs versions before 0.14.3 are vulnerable to remote code execution through the "Rebase before merging" pull request merge option. An authenticated user who can create a pull request, such as any user who owns a repository with rebase merging enabled, can use a crafted branch name to inject a git option that runs attacker-chosen commands on the server. Upgrade to Gogs 0.14.3, which contains the fix.
