ruby-crass: Crass is a Ruby CSS parser that is compliant with the CSS Syntax Level 3 specification
CVE-2026-116695 is fixed in ruby-crass on 1 platform by DEBIAN-CVE-2026-116695 (version 1.0.8-1), released October 28, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Crass is a Ruby CSS parser that is compliant with the CSS Syntax Level 3 specification. Prior to 1.0.8, Crass incorrectly treats a closing parenthesis after an escaped backslash as escaped while consuming the remnants of a bad URL. Crass therefore keeps declarations, style rules, or at-rules inside a bad URL token even though a browser treats them as live CSS. A sanitizer that parses untrusted CSS with Crass and reserializes it without rejecting the bad URL can allow CSS used for UI redress, external resource loading, or CSS-based data exfiltration, but this issue does not enable script execution in modern browsers. This issue is fixed in version 1.0.8.
