With valid login credentials, URL Redirection to Untrusted Site ('Open Redirect'), Server-Side Request Forgery (SSRF) vulnerability in Apache Shiro.




This issue affects Apache Shiro from 2.0-alpha to 2.1.0, and 3.0.0-alpha-1, only when using shiro-jakarta-ee integration module.

Users are recommended to upgrade to version 2.1.1, or 3.0.0-alpha-2 or later, which fixes the issue by encrypting the cookie.

After successful login, Jakarta EE integration module uses shiroSavedRequest cookie to redirect to a particular web page after login.
This cookie was not validated, and can be forged to send a HTTP GET request from the server itself to an arbitrary URL from the cookie.
