  - KaTeX is a JavaScript library for TeX math rendering on the web. KaTeX users who render untrusted
    mathematical expressions could encounter malicious input using `\def` or `\newcommand` that causes a near-
    infinite loop, despite setting `maxExpand` to avoid such loops. KaTeX supports an option named maxExpand
    which aims to prevent infinitely recursive macros from consuming all available memory and/or triggering a
    stack overflow error. Unfortunately, support for Unicode (sub|super)script characters allows an attacker
    to bypass this limit. Each sub/superscript group instantiated a separate Parser with its own limit on
    macro executions, without inheriting the current count of macro executions from its parent. This has been
    corrected in KaTeX v0.16.10. (CVE-2024-28244)

Note that Nessus relies on the presence of the package as reported by the vendor.");
