CVE-2026-63670
Last modified
CVE-2026-63670 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. ApostropheCMS is an open-source Node.js content management system. Prior to 2.17.6, sanitizeHtml() can pass disallowed executable markup through packages/sanitize-html/index.js when textarea or xmp is included in allowedTags because a literal solidus after the raw-text end-tag name is treated as text by htmlparser2 and the ontext handler emits that content without escaping, while a browser parses the following img onerror markup as active HTML. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
