Severity: Affected versions:
- Apache Shiro (org.apache.shiro:shiro-jakata-ee) 2.0.0-alpha-0 through 3.0.0 Description: When Apache Shiro is used with the Jakarta EE integration module, a low-privileged user can craft an HTTP request that causes the server to initiate a connection to an attacker-controlled URL and transmit attacker-controlled data. This vulnerability affects Apache Shiro versions 2.x through 3.0.0 only in deployments that use the Jakarta EE integration module. Mitigation: Upgrade to version 3.0.1 or later, which fixes the issue. + Alternatively, you can set the `org.apache.shiro.form-resubmit-host` (String) and `org.apache.shiro.form-resubmit-port` (Integer) system properties to restrict the host and port that Shiro will connect to when resubmitting a form.
