EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 1.5%, top 29% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
