| Doc Text: |
A flaw was found in soupsieve, a CSS selector library. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by supplying specially crafted, untrusted CSS selector strings. The flaw occurs due to a regular expression vulnerable to catastrophic backtracking when processing an attribute selector with an unterminated quoted value, leading to CPU exhaustion.
