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.

 https://cve.radiocsirt.org/vuln/ghsa-fmx4-26r3-wxpf GHSA-fmx4-26r3-wxpf — Integer overflow in cmark-gfm table parsing extension leads to heap memory corruption 2026-10-05T07:21:56.146713+00:00

Affected: RubyGems: commonmarker

### Impact

CommonMarker uses `cmark-gfm` for rendering [Github Flavored Markdown](https://github.github.com/gfm/). An [integer overflow in `cmark-gfm`'s table row parsing](https://github.com/github/cmark-gfm/security/advisories/GHSA-mc3g-88wq-6f4x) may lead to heap memory corruption when parsing tables who's marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution.

If affected versions of CommonMarker are used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE).

### Patches

This vulnerability has been patched in the following CommonMarker release:

- v0.23.4

### Workarounds

The vulnerability exists in the table markdown extensions of `cmark-gfm`. Disabling any use of the table extension will prevent this vulnerability from being triggered.
