CVE-2026-73273 · Gitea Maven checksum upload quota bypass and memory exhaustion
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Gitea's Maven upload handler reads checksum uploads entirely into memory and returns before enforcing package-size quotas. An authenticated user with package-publish permission can submit an oversized body to a checksum endpoint despite legitimate checksum values being at most 128 bytes. This bypasses the upload quota on that path and can exhaust server memory.
