ruby-crass: Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification
CVE-2026-61847 is fixed in ruby-crass on 1 platform by DEBIAN-CVE-2026-61847 (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, when the `:preserve_comments` option is not enabled, which is the default, Crass discards CSS comments by recursively consuming the next token. An attacker-provided stylesheet containing a very large number of adjacent comments can cause excessive recursion and trigger a `SystemStackError`, denying service to the parsing application. Preserving comments avoids this recursive path. This issue is fixed in version 1.0.7.
