Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Shiro's shiro-jakarta-ee module, versions 2.0-alpha through 2.2.0 and 3.0.0-alpha-1, used the HTTP Referer header to choose the redirect target after login. An attacker who can influence that header could steer users to a different redirect destination. Upgrade to shiro-jakarta-ee 2.2.1 or 3.0.0-alpha-2.
