How to Fix CVE-2026-40178

To remediate this vulnerability, upgrade all affected Ajenti.plugin.core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ajenti.plugin.core fixed: 0.112 
pip install ajenti.plugin.core>=0.112
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show ajenti.plugin.core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-40178, inspect your installed packages using pip:

pip show ajenti.plugin.core

Analyze the terminal output to locate any version of Ajenti.plugin.core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.112), your application is affected.

Note: The pip show ajenti.plugin.core command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Ajenti.plugin.core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If the 2FA was activated, it was possible during a short moment after the authentication of an user to bypass its authentication. ### Patches This is fixed in the version 0.112. Users should upgrade to this version as soon as possible.
