NewCVE-2026-113650 (opens in a new tab)How to fix?
Upgrade sanitize-html to version 2.18.1 or higher.
Overview
sanitize-html is a library that allows you to clean up user-submitted HTML, preserving whitelisted elements and whitelisted attributes on a per-element basis
Affected versions of this package are vulnerable to Uncontrolled Recursion via its transitive dependency on deepmerge, which is affected by CVE-2026-93753. When sanitize-html merges configuration objects combining tag-specific and wildcard allowedClasses or allowedStyles entries, the deepmerge call could be exploited to cause a crash. The fix removes the deepmerge dependency entirely, replacing it with simple array concatenation.
