How to Fix CVE-2026-44364

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

misp-modules fixed: Latest secure release 
pip install misp-modules>=Latest secure release
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 misp-modules

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-44364, inspect your installed packages using pip:

pip show misp-modules

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

Note: The pip show misp-modules command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Misp modules, 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

A Cross-Site Request Forgery vulnerability in the MISP Modules website allowed an attacker to cause an authenticated user to submit unintended requests to the home endpoint. The vulnerability was due to the home blueprint being exempted from CSRF protection. This could allow modification of session query data in the context of the authenticated user. The issue was fixed by enabling CSRF protection for the affected blueprint and hardening query parsing. As reported by Bilal Teke.
