How severe is GHSA-qj6r-fhrc-jj5r?

GHSA-qj6r-fhrc-jj5r has a CVSS score of 7/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-qj6r-fhrc-jj5r?

GHSA-qj6r-fhrc-jj5r affects the following packages: github.com/hyperledger/fabric (Go). Ecosystems affected: Go.

How do I fix GHSA-qj6r-fhrc-jj5r?

Update github.com/hyperledger/fabric to 2.4.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qj6r-fhrc-jj5r is resolved across your whole dependency graph.

How do I detect GHSA-qj6r-fhrc-jj5r in my Go dependencies?

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

How do I mitigate GHSA-qj6r-fhrc-jj5r 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.

Is GHSA-qj6r-fhrc-jj5r actively exploited in the wild?

No public exploit code has been indexed for GHSA-qj6r-fhrc-jj5r 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-qj6r-fhrc-jj5r?

GHSA-qj6r-fhrc-jj5r has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 67th 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-qj6r-fhrc-jj5r?

GHSA-qj6r-fhrc-jj5r is classified as Improper Input Validation (CWE-20). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-qj6r-fhrc-jj5r published, and has it been updated?

GHSA-qj6r-fhrc-jj5r was published on October 13, 2022 and was last updated on July 18, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
