UBUNTU-CVE-2026-44598 (CVE-2026-44598)

Vulnerability from osv_ubuntu – Published: 2026-05-25 21:16 – Updated: 2026-05-29 17:49 – Source website

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
