How do I fix GHSA-c2gg-rrhc-fvvg?

Update magento/community-edition to 2.1.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c2gg-rrhc-fvvg is resolved across your whole dependency graph.

How do I detect GHSA-c2gg-rrhc-fvvg in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for magento/community-edition. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-c2gg-rrhc-fvvg 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-c2gg-rrhc-fvvg?

O3 pinpoints whether GHSA-c2gg-rrhc-fvvg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-c2gg-rrhc-fvvg actively exploited in the wild?

No public exploit code has been indexed for GHSA-c2gg-rrhc-fvvg 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-c2gg-rrhc-fvvg?

GHSA-c2gg-rrhc-fvvg has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 64th 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-c2gg-rrhc-fvvg?

GHSA-c2gg-rrhc-fvvg is classified as Insufficient Random Values (CWE-330). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-c2gg-rrhc-fvvg published, and has it been updated?

GHSA-c2gg-rrhc-fvvg was published on May 24, 2022 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
