ruby-crass: Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification
CVE-2026-61845 is fixed in ruby-crass on 1 platform by DEBIAN-CVE-2026-61845 (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 converts `CSS scientific notation` number values with unbounded exponentiation before clamping the result to `Float::MAX`. Applications that use Crass to parse attacker-controlled CSS strings can be forced to spend disproportionate CPU and memory parsing a tiny input, potentially resulting in a crash. This issue is fixed in version 1.0.7.
