Name of the Vulnerable Software and Affected Versions
commonmark versions 1.5.0 through 2.8.3
Description
The Footnote extension fails to deduplicate footnote definitions. This allows attackers to craft documents with duplicate footnote definitions and references to trigger quadratic output expansion, which consumes excessive memory and CPU to exhaust server resources, resulting in a denial of service.
Recommendations
Update commonmark to version 2.8.4 or later.
