Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-407.

Summary

Gitea through 1.27.3 is affected. When processing issue and comment bodies, Gitea rescans the preceding text for action keywords once per Markdown link, so processing time grows quadratically with input size (CWE-407). An authenticated user who can submit issue or comment content can send a body of about 1 MB that keeps a CPU core busy for several minutes while a database transaction stays open.

Description from the CNA

When processing issue and comment bodies, Gitea scanned the entire preceding text for action keywords such as "closes" or "fixes" once per Markdown link, giving processing time quadratic in the input size. An authenticated user able to submit issue or comment content could send a crafted body of about 1 MB that keeps a CPU core busy for several minutes while holding a database transaction open.
