Detection & IOCsextracted from sources · hover to see the quote
- →An authenticated attacker creates an oversized Issue description via GraphQL API; repeated retrieval of this issue saturates CPU usage — monitor for abnormally large GraphQL mutation payloads targeting Issue description fields combined with high-frequency read requests for the same issue. ↗
- ·Affected versions span a very wide range (8.3 through 16.0.1); fixed versions are 15.10.8, 15.11.7, and 16.0.2 — ensure GitLab CE/EE is patched to one of these releases. ↗
- ·Debian sid resolves the issue with package version 15.10.8+ds1-2; verify the installed package version on Debian-based deployments. ↗
