      <title>CVE-2024-28244 — KaTeX's maxExpand bypassed by Unicode sub/superscripts</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-28244</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; KaTeX&lt;/p&gt;
&lt;p&gt;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 &amp;#34;Unicode (sub|super)script characters&amp;#34; 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.&lt;/p&gt;</description>
