How to Fix CVE-2026-6109

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

metagpt fixed: Latest secure release 
pip install metagpt>=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 metagpt

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-6109, inspect your installed packages using pip:

pip show metagpt

Analyze the terminal output to locate any version of Metagpt 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 metagpt 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 Metagpt, 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 vulnerability was determined in FoundationAgents MetaGPT up to 0.8.2. The impacted element is the function evaluateCode of the file metagpt/environment/minecraft/mineflayer/index.js of the component Mineflayer HTTP API. Executing a manipulation can lead to cross-site request forgery. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
