Which packages are affected by GHSA-3qh4-r86r-grvm?

GHSA-3qh4-r86r-grvm affects the following packages: typed-function (npm). Ecosystems affected: npm.

How do I fix GHSA-3qh4-r86r-grvm?

Update typed-function to 0.10.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3qh4-r86r-grvm is resolved across your whole dependency graph.

How do I detect GHSA-3qh4-r86r-grvm in my npm dependencies?

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

How do I mitigate GHSA-3qh4-r86r-grvm if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is GHSA-3qh4-r86r-grvm actively exploited in the wild?

No public exploit code has been indexed for GHSA-3qh4-r86r-grvm yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-3qh4-r86r-grvm?

GHSA-3qh4-r86r-grvm has an EPSS (Exploit Prediction Scoring System) score of 1.9%, placing it in the 79th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-3qh4-r86r-grvm?

GHSA-3qh4-r86r-grvm is classified as Code Injection (CWE-94), Improper Input Validation (CWE-20). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-3qh4-r86r-grvm published, and has it been updated?

GHSA-3qh4-r86r-grvm was published on September 2, 2020 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
