GHSA-836r-79rf-4m37: Soup Sieve: Regular Expression Denial of Service (ReDoS) via Selector ParserCVE-2026-49477 0 A Regular Expression Denial of Service (ReDoS) vulnerability exists in soupsieve's CSS selector parser due to catastrophic backtracking in a regex pattern when processing attribute selectors with unterminated quoted values. This can cause the regex engine to hang for several seconds with a payload of only 300 bytes. The issue affects any application that compiles untrusted CSS selectors using soupsieve versions prior to 2.8.4. The attack is CPU-bound, causing thread blocking without memory exhaustion.
