ruby-crass: Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification
CVE-2026-61846 is fixed in ruby-crass on 1 platform by DEBIAN-CVE-2026-61846 (version 1.0.7-1), released October 31, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification. Prior to 1.0.7, Crass recursively parses `CSS simple blocks and functions` without a depth guard. An attacker-controlled CSS value containing deeply nested blocks or functions can recurse until Ruby raises `SystemStackError`: stack level too deep, or cause excessive memory usage. Version 1.0.7 adds a configurable depth limit with a conservative default. This issue is fixed in version 1.0.7.
