  - 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.
