{"id":"CVE-2026-61846","published":"2026-10-30T19:18:28.370","lastModified":"2026-10-30T19:39:14.897","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-674"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rgrove/crass/commit/cf68287356ec6e20d51cfc4a2d0c3912b7334e99","tags":[]},{"url":"https://github.com/rgrove/crass/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/rgrove/crass/security/advisories/GHSA-6jxj-px6v-747w","tags":[]}],"exploitRefs":[{"url":"https://github.com/rgrove/crass/commit/cf68287356ec6e20d51cfc4a2d0c3912b7334e99","tags":[]},{"url":"https://github.com/rgrove/crass/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/rgrove/crass/security/advisories/GHSA-6jxj-px6v-747w","tags":[]}],"hasPoc":true,"ai":null}
