medium Tenable Cloud Security Plugin ID 459629

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Authentication Bypass by Alternate Name vulnerability in Apache Shiro. This issue affects Apache Shiro:
 before 2.0.7. Users are recommended to upgrade to version 2.0.7, which fixes the issue. The issue only
 effects static files. If static files are served from a case-insensitive filesystem, such as default macOS
 setup, static files may be accessed by varying the case of the filename in the request. If only lower-case
 (common default) filters are present in Shiro, they may be bypassed this way. Shiro 2.1.0 and later has a
 new parameters to remediate this issue shiro.ini: filterChainResolver.caseInsensitive = true
 application.properties: shiro.caseInsensitive=true Shiro 3.0.0 and later makes this the default in
 shiro.ini-based configurations. Shiro 3.0.1 and later makes this the default in all configurations,
 including programmatic and Spring / Spring Boot. (CVE-2026-23903)
