MathJax < 3.0.0 Regular Expression Denial of Service

Synopsis

MathJax < 3.0.0 Regular Expression Denial of Service

Description

According to its self-reported version number, MathJax is prior to 3.0.0. Therefore, it may be affected by two Regular Expression Denial of Service (ReDoS) vulnerabilities in MathJax.js via the components pattern and markdownPattern. Note that the vendor disputes this issue because the regular expressions are not applied to user input.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MathJax version 3.0.0 or later.
