**Name of the Vulnerable Software and Affected Versions** GitHub Flavored Markdown versions prior to 0.29.0.gfm.1 **Description** The issue is related to the time complexity of parsing certain markdown tables, which can take O(n * n) time. An attacker could craft a markdown table to cause a denial of service. This issue does not affect the upstream cmark project. **Recommendations** For versions prior to 0.29.0.gfm.1, update to version 0.29.0.gfm.1 to resolve the issue. As a temporary workaround, consider restricting the use of markdown tables until the update is applied.
