How to Fix GHSA-w228-rfpx-fhm4

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

cg fixed: 60.2.12 
pip install cg>=60.2.12
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 cg

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-w228-rfpx-fhm4, inspect your installed packages using pip:

pip show cg

Analyze the terminal output to locate any version of Cg in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 60.2.12), your application is affected.

Note: The pip show cg 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 Cg, 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

### Summary A vulnerability has been discovered in the handling of the referrer header in the application, which could allow an attacker to conduct open redirects. The issue arises from improper validation of the referrer header in certain conditions. By manipulating the referrer header, an attacker could potentially redirect users to malicious websites, phishing pages, or other dangerous destinations. ### PoC If you change the referer header, you will be redirected to that domain without verifying. https://github.com/Clinical-Genomics/cg/blob/master/cg/server/invoices/views.py#L173 ### Impact An attacker exploiting this vulnerability could trick users into visiting malicious websites or disclose sensitive information by redirecting them to unintended destinations. This could lead to various attacks including phishing, malware distribution, or further exploitation of other vulnerabilities.
