URL validation bypass cheat sheet for SSRF/CORS/Redirect - 2024 Edition
Summary: PortSwigger published a URL validation bypass cheat sheet containing payloads for evading URL validation, aimed at attacks including server-side request forgery, CORS misconfigurations, and open redirection. The page describes the wordlists as useful for those three attack types but provides no payload details or findings in the text.
Bottom line: A public wordlist of URL validation bypasses means attackers can test your SSRF, CORS, and redirect defenses against known evasion patterns rather than inventing them, so any validator that only checks the literal URL string is already covered by this list.
