How to Fix CVE-2026-6111

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-2026-6111, 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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 security flaw has been discovered in FoundationAgents MetaGPT up to 0.8.2. This impacts the function decode_image of the file metagpt/utils/common.py. The manipulation of the argument img_url_or_b64 results in server-side request forgery. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
