What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Grav Git Sync 1.0.2 through 3.4.12 contains a command injection vulnerability that allows authenticated content editors to execute OS commands by injecting shell substitutions into profile fields. When the gravuser or gravfull author mode is enabled, attackers can set a malicious username, full name, or email that reaches PHP exec() via git commit --author, running commands as the web-server account.
