CVE-2026-54705: Arnog Mathlive

Medium severity, CVSS 6.3. EPSS: 0.4% chance of exploitation in the next 30 days.

MathLive provides web components for math display and input. Prior to 0.110.0, MathLive fails to escape text-mode content in \text{} and \mbox{} commands in Box.toMarkup at src/core/box.ts, in xmlEscape, scanText, and text-mode output in src/formats/atom-to-math-ml.ts, and through convertLatexToMarkup, convertLatexToMathMl, <math-span>, <math-div>, and the default identity MathfieldElement.createHTML, allowing malicious input to run arbitrary JavaScript when rendered. This issue is fixed in version 0.110.0.

Affected products

• Arnog Mathlive: before 0.110.0 (fixed in 0.110.0)
