How to Fix CVE-2021-28125

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

superset fixed: Latest secure release 
pip install superset>=Latest secure release
apache-superset fixed: 1.1.0 
pip install apache-superset>=1.1.0
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 superset

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2021-28125, inspect your installed packages using pip:

pip show superset

Analyze the terminal output to locate any version of Superset in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Superset, 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

Apache Superset prior to 1.1.0 allowed for the creation of an external URL that could be malicious. By not checking user input for open redirects the URL shortener functionality would allow for a malicious user to create a short URL for a dashboard that could convince the user to click the link.
