Name of the Vulnerable Software and Affected Versions
commonmark versions 2.0.0 through 2.8.3
Description
A denial of service issue exists in the
XmlRenderer component, which generates depth-proportional indentation for every XML tag. An attacker can supply deeply nested Markdown or Abstract Syntax Tree (AST) structures to trigger quadratic memory consumption and output amplification, leading to the exhaustion of server resources.Recommendations
Update commonmark to version 2.8.4 or later.
