Weblate: Remote code execution during backup restoration
### Impact
The project backup didn't filter Git and Mercurial configuration files and this could lead to remote code execution under certain circumstances.
### Patches
*
https://github.com/WeblateOrg/weblate/pull/18549
### Workarounds
The project backup is only accessible to users who can create projects. Restricting access to this limits scope of the vulnerability.
