Vulnerability details
The vulnerability allows a remote attacker to redirect users to an attacker-controlled URL after login.
The vulnerability exists due to improper input validation in CookieRequestCache and CookieServerRequestCache when processing the REDIRECT_URI cookie for post-login redirection. A remote attacker can influence the value of the REDIRECT_URI cookie to redirect users to an attacker-controlled URL after login.
