No CVSS score has been assigned to GHSA-392h-r46j-q24p yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-392h-r46j-q24p?

GHSA-392h-r46j-q24p affects the following packages: github.com/owncast/owncast (Go). Ecosystems affected: Go.

How do I fix GHSA-392h-r46j-q24p?

The records we use list no patched version of github.com/owncast/owncast for GHSA-392h-r46j-q24p. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

How do I detect GHSA-392h-r46j-q24p in my Go dependencies?

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

How do I mitigate GHSA-392h-r46j-q24p 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-392h-r46j-q24p actively exploited in the wild?

No public exploit code has been indexed for GHSA-392h-r46j-q24p 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-392h-r46j-q24p?

GHSA-392h-r46j-q24p has an EPSS (Exploit Prediction Scoring System) score of 1.6%, placing it in the 76th 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-392h-r46j-q24p?

GHSA-392h-r46j-q24p is classified as Server-Side Request Forgery (SSRF) (CWE-918), Code Injection (CWE-94). 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-392h-r46j-q24p published, and has it been updated?

GHSA-392h-r46j-q24p was published on November 28, 2023 and was last updated on November 28, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Proof-of-concept exploit code exists

CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
