How to Fix CVE-2026-7725

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

prefect fixed: 3.6.25.dev7 
pip install prefect>=3.6.25.dev7
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 prefect

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-7725, inspect your installed packages using pip:

pip show prefect

Analyze the terminal output to locate any version of Prefect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.25.dev7), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Prefect, 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 found in PrefectHQ prefect up to 3.6.25.dev6. Affected by this issue is some unknown functionality of the file src/prefect/runner/storage.py of the component GitRepository Pull Handler. The manipulation of the argument commit_sha/directories results in argument injection. It is possible to launch the attack remotely. The exploit has been made public and could be used. Upgrading to version 3.6.25.dev7 can resolve this issue. The patch is identified as 6a9d9918716ce4ee0297b69f3046f7067ef1faae. It is advisable to upgrade the affected component.
