Description
CakePHP through 5.4.3 contains an improper cookie domain validation vulnerability in the Http Client CookieCollection that allows malicious servers to receive and plant cookies by abusing unanchored suffix matching. Attackers controlling a host such as one ending in a victim domain suffix, or sending Set-Cookie Domain values for unrelated hosts, can steal session cookies or inject cookies into shared client cookie jars.
