CVE-2026-44598: CWE-601 URL Redirection to Untrusted Site ('Open Redirect') in Apache Software Foundation Apache Shiro Jakarta EE module
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.
AI Analysis
Technical Summary
The vulnerability in Apache Shiro's Jakarta EE integration module arises from improper validation of the shiroSavedRequest cookie used for redirecting users after login. Attackers with valid credentials can forge this cookie to cause the server to perform HTTP GET requests to arbitrary URLs, leading to open redirect and SSRF conditions. Affected versions include 2.0-alpha through 2.1.0 and 3.0.0-alpha-1. The vendor fixed the issue by encrypting the cookie starting with versions 2.1.1 and 3.0.0-alpha-2.
Potential Impact
An attacker who has valid login credentials can exploit this vulnerability to redirect users to untrusted sites and cause the server to send HTTP GET requests to arbitrary URLs. This can facilitate phishing or SSRF attacks, potentially exposing internal resources or enabling further attacks. The CVSS 4.0 base score is 5.1, indicating a medium severity impact.
Mitigation Recommendations
Users should upgrade Apache Shiro Jakarta EE module to version 2.1.1 or 3.0.0-alpha-2 or later, where the vulnerability is fixed by encrypting the shiroSavedRequest cookie. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending these versions.
