GHSA-W228-RFPX-FHM4

cg vulnerable to an Open Redirect Vulnerability on Referer Header

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.

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.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

GHSA-W228-RFPX-FHM4 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (60.2.12); upgrading removes the vulnerable code path.

1. What is GHSA-W228-RFPX-FHM4? GHSA-W228-RFPX-FHM4 is a medium-severity open redirect vulnerability in cg (pip), affecting versions < 60.2.12. It is fixed in 60.2.12. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is GHSA-W228-RFPX-FHM4? GHSA-W228-RFPX-FHM4 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of cg are affected by GHSA-W228-RFPX-FHM4? cg (pip) versions < 60.2.12 is affected.
4. Is there a fix for GHSA-W228-RFPX-FHM4? Yes. GHSA-W228-RFPX-FHM4 is fixed in 60.2.12. Upgrade to this version or later.
5. Is GHSA-W228-RFPX-FHM4 exploitable, and should I be worried? Whether GHSA-W228-RFPX-FHM4 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-W228-RFPX-FHM4 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-W228-RFPX-FHM4? Upgrade cg to 60.2.12 or later.
