CVE-2026-58301
Apache Shiro: Server-side POST request may be steered to an alternate host
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.
