ruby-loofah: Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri
CVE-2026-73490 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-73490, released August 15, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Prior to 2.25.2, Loofah's HTML5 sanitizer applies its local-reference restriction only to the xlink:href attribute on SVG use and feImage elements, while browsers also accept the plain href attribute. A crafted sanitized SVG can therefore reference an arbitrary same-origin external document; use may render external SVG content containing scripts or other dangerous content, and feImage may load external images for tracking. Applications that sanitize user-supplied SVG with Loofah's default allowlist are affected. This issue is fixed in version 2.25.2.
