GHSA-836r-79rf-4m37 | Soup Sieve: Regular Expression Denial of Service (ReDoS) via Selector Parser |
Tue, 14 Jul 2026 21:15:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4. Prior to 2.8.4, the CSS selector parser in soupsieve contains a regular expression vulnerable to catastrophic backtracking when processing an attribute selector with an unterminated quoted value in soupsieve/css_parser.py, allowing an attacker who can supply untrusted CSS selector strings to soupsieve.compile() or Beautiful Soup .select() / .select_one() to cause CPU exhaustion and denial of service. This issue is fixed in version 2.8.4. | |
