SCA: security update for katex (GHSA-238p-pmpm-9mq7)

low Tenable Cloud Security Plugin ID 472983

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. From 0.11.0 until
 0.18.2, KaTeX uses ordinary JavaScript property access for the renderer options object, the trust setting,
 default and processor setting metadata, and namespace lookup and group restoration, allowing inherited
 properties to be treated as explicitly supplied values. When Object.prototype is already polluted or an
 attacker controls the options object's prototype, attacker-controlled mathematical expressions can use an
 inherited trust value to enable trusted rendering and produce links capable of user-interaction cross-site
 scripting or loading attacker-selected external resources in a consuming application that inserts
 unsanitized KaTeX output into a page. KaTeX does not itself create the prototype pollution, and rendering
 an expression alone does not execute script. This issue is fixed in version 0.18.2. (CVE-2026-103923)

Solution

Update the katex library and its related packages to version 0.18.2 or later.
