CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/S:P/AU:Y/V:D/RE:L/U:Green
Affected versions:
- Apache Shiro (org.apache.shiro:shiro-spring) 3.0.1 before 3.0.2
Description:
The fix for CVE-2026-23903
https://shiro.apache.org/security-reports.html#cve_2026_23903 was incomplete
for manually-created ShiroFilterFactoryBean, which still matched paths
case-sensitively by default.
This issue affects Apache Shiro version 3.0.1, only when ShiroFilterFactoryBean
is created manually by the application and static files are served from a
case-insensitive filesystem.
Applications that let Shiro Spring (Boot) Starter create the bean are not
affected.
Mitigation: Upgrade to version 3.0.2 or later, which fixes the issue.
Alternatively, call setCaseInsensitive(true) on the ShiroFilterFactoryBean.
