CVE-2022-0488Network attack vector

Service interruption via crafted Markdown block quotes

Published Mar 28, 2022 · Updated Aug 2, 2024

Resource exhaustion in GitLab CE/EE 8.10 through 14.5.3, 14.6.0 through 14.6.3, and 14.7.0 allows remote authenticated users to cause timeouts. The Markdown rendering path times out while processing content containing a specific quantity of block quotes; GitLab has not disclosed the exact faulty function or operation. An authenticated user must place the crafted Markdown where it will be rendered, and GitLab's assessment requires another user's interaction; the reported consequence is limited to availability.
