Which packages are affected by GHSA-w228-rfpx-fhm4?

GHSA-w228-rfpx-fhm4 affects the following packages: cg (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-w228-rfpx-fhm4?

Update cg to 60.2.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w228-rfpx-fhm4 is resolved across your whole dependency graph.

How do I detect GHSA-w228-rfpx-fhm4 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cg, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-w228-rfpx-fhm4 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-w228-rfpx-fhm4?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-w228-rfpx-fhm4 can be triaged on real exposure rather than presence alone.

Description

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.

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.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cg, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update cg to 60.2.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w228-rfpx-fhm4 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
