Summary
Gitea pre-receive hook permission cache allows full repository write access
Details

Gitea 1.25.5 caches a branch-specific write-permission result across multiple refs in one pre-receive hook session, allowing a per-branch maintainer-edit grant to be reused for other refs and escalate to full repository write access.
