Summary
Embedded malware in rc
The npm package rc had versions published with malicious code. Users of affected versions (1.2.9, 1.3.9, and 2.3.9) should downgrade to 1.2.8 as soon as possible and check their systems for suspicious activity.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Which versions of rc are affected by GHSA-G2Q5-5433-RHRF? rc (npm) versions = 1.2.9 is affected.
- Is there a fix for GHSA-G2Q5-5433-RHRF? No fixed version is listed for GHSA-G2Q5-5433-RHRF yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-G2Q5-5433-RHRF exploitable, and should I be worried? Whether GHSA-G2Q5-5433-RHRF 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.

- What actually determines whether GHSA-G2Q5-5433-RHRF 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.
