CVE-2024-22051 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. CommonMarker versions prior to 0.23.4 are at risk of an integer overflow vulnerability. This vulnerability can result in possibly unauthenticated remote attackers to cause heap memory corruption, potentially leading to an information leak or remote code execution, via parsing tables with marker rows that contain more than UINT16_MAX columns.. EPSS estimates a 1.45% chance of exploitation in the next 30 days.
