Summary
In Gitea before version 1.25.5, validation constraints for repository creation fields are missing, including length-limited template fields and trust model or object format values.
Risk Assessment
Lack of validation may allow an attacker to inject malformed data, potentially leading to unexpected behavior or compromise of repository integrity.
Recommendation
It is recommended to immediately upgrade Gitea to version 1.25.5 or later, which includes the necessary validation fixes.
