CVE-2024-28244
CVSS 3.1 Score 6.5 of 10 (medium)
Details
Summary
CVE-2024-28244 is a vulnerability affecting KaTeX, a JavaScript library used for TeX math rendering on the web. Malicious input utilizing `\\def` or `\\newcommand` can trigger near-infinite loops, potentially causing memory exhaustion or stack overflow errors. KaTeX offers a preventative measure called maxExpand to avoid such loops. However, the vulnerability lies in the library's handling of Unicode (sub|super)script characters. Each sub/superscript group initializes a new Parser instance, allowing an attacker to bypass the maxExpand limit, leading to potential memory exhaustion or stack overflow. A fix for this issue is available in KaTeX version 0.16.10.
