AI Analysis
Technical Summary
The vulnerability CVE-2026-41891 affects ci4ms versions >=0.26.0 and <0.31.8.0. The auth filter responsible for checking if a user is deactivated or banned is disabled (commented out), resulting in insufficient session expiration as per CWE-613. This means sessions for users who should be deactivated or banned may remain valid, potentially allowing unauthorized access. The vulnerability has a CVSS 4.0 score of 5.3 (medium severity) and was published on 2026-05-07. The issue is fixed in version 0.31.8.0.
Potential Impact
Users who have been deactivated or banned may retain active sessions due to the missing check in the auth filter, potentially allowing them to continue accessing the system when they should not. This could lead to unauthorized access and misuse of privileges. There are no known exploits in the wild as of the publication date.
Mitigation Recommendations
Upgrade ci4ms to version 0.31.8.0 or later, where the auth filter properly enforces the deactivated/banned user check. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor's versioning information.
