How to Fix GHSA-f54f-hr32-586f

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

browser-use fixed: 0.1.45 
pip install browser-use>=0.1.45
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 browser-use

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-f54f-hr32-586f, inspect your installed packages using pip:

pip show browser-use

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.45), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-647: Use of Non-Canonical URL Paths for Authorization Decisions, where the product defines policy namespaces and makes authorization decisions based on the assumption that a url is canonical. this can allow a non-canonical url to bypass the authorization. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing.
