{"id":"CVE-2026-61845","published":"2026-10-30T19:18:28.197","lastModified":"2026-10-30T20:17:11.263","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-789"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rgrove/crass/commit/ea6726b7f7cf7e85b23aa2240b8512b4f8d11ad9","tags":[]},{"url":"https://github.com/rgrove/crass/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/rgrove/crass/security/advisories/GHSA-6wmf-3r64-vcwv","tags":[]}],"exploitRefs":[{"url":"https://github.com/rgrove/crass/commit/ea6726b7f7cf7e85b23aa2240b8512b4f8d11ad9","tags":[]},{"url":"https://github.com/rgrove/crass/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/rgrove/crass/security/advisories/GHSA-6wmf-3r64-vcwv","tags":[]}],"hasPoc":true,"ai":null}
