CVE-2025-29771: Jitbit Htmlsanitizer

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

HtmlSanitizer is a client-side HTML Sanitizer. Versions prior to 2.0.3 have a cross-site scripting vulnerability when the sanitizer is used with a `contentEditable` element to set the elements `innerHTML` to a sanitized string produced by the package. If the code is particularly crafted to abuse the code beautifier, that runs AFTER sanitation. The issue is patched in version 2.0.3.

Affected products

• Jitbit Htmlsanitizer: before 2.0.3 (fixed in 2.0.3)
