GHSA-MXM6-V9R6-R94C @nuxtjs/mdc's URL sanitizer misses SVG xlink:href and data:text/html, allowing XSS from untrusted markdown at the default configuration

Summary @nuxtjs/mdc renders untrusted markdown including raw HTML to a Vue component tree. Across two prior advisories it added a URL/attribute sanitizer to block dangerous links in that HTML: validateProps / validateProp and an unsafeLinkPrefix deny-list dist/runtime/parser/utils/props.js. The...

CVE-2026-63671

@nuxtjs/mdc prior to 0.22.1 contains two gaps in its default URL sanitizer that enable cross-site scripting (XSS) from untrusted Markdown. First, validateProp checks only attributes named href or src, so an SVG xlink:href value (represented as xLinkHref) retains a javascript: URL that executes in...
