CVE	Severity	Published▾	Status	Exploitation	Description
CVE-2026-43827	Medium	2026-05-25	No exploit published	No public exploit	Default configurations of Apache Shiro have a session fixation vulnerability. This issue affects Apache Shiro from 1.0 to 2.1.0, and 3.0.0-alpha-1. Users are recommended to upgrade to version 2.1.1, or 3.0.0-alpha-2 or later, which fixes the issue. In the affected versions, when a session already exists, it is not invalidated upon successful login, nor is a new session being generated with a new ID.
CVE-2023-46749	Medium	2024-01-15	Protected by Waratek	No public exploit	Apache Shiro before 1.13.0 or 2.0.0-alpha-4, may be susceptible to a path traversal attack that results in an authentication bypass when used together with path rewriting Mitigation: Update to Apache Shiro 1.13.0+ or 2.0.0-alpha-4+, or ensure `blockSemicolon` is enabled (this is the default).
