Summary
Vulnerability in org.apache.shiro:shiro-jakarta-ee (CVE-2026-48589). Risk of unauthorized operations or information disclosure. Exploitable via Referer header. Mitigation: upgrade to 3.0.0-alpha-2 or later.
Original description
The description as published by the source.
Apache Shiro’s Jakarta EE module used the HTTP Referer header in certain cases to issue redirect after a user login.
In affected versions, insufficient validation of this client-controlled value could allow an attacker to influence the redirect target in applications using the Jakarta EE module.
This issue affects Apache Shiro from 2.0-alpha to 2.2.0, and 3.0.0-alpha-1, only when using shiro-jakarta-ee integration module.
