CVE-2024-28244 Information

Description

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 �nicode (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.
