Which packages are affected by GHSA-fr62-mg2q-7wqv?

GHSA-fr62-mg2q-7wqv affects the following packages: github.com/matrix-org/pinecone (Go). Ecosystems affected: Go.

How do I fix GHSA-fr62-mg2q-7wqv?

No patched version of github.com/matrix-org/pinecone has shipped for GHSA-fr62-mg2q-7wqv yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect GHSA-fr62-mg2q-7wqv in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/matrix-org/pinecone. 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-fr62-mg2q-7wqv 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-fr62-mg2q-7wqv?

O3 pinpoints whether GHSA-fr62-mg2q-7wqv 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-fr62-mg2q-7wqv actively exploited in the wild?

No public exploit code has been indexed for GHSA-fr62-mg2q-7wqv 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-fr62-mg2q-7wqv?

GHSA-fr62-mg2q-7wqv has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 12th 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-fr62-mg2q-7wqv?

GHSA-fr62-mg2q-7wqv is classified as Cross-site Scripting (XSS) (CWE-79), CWE-80 (CWE-80). 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-fr62-mg2q-7wqv published, and has it been updated?

GHSA-fr62-mg2q-7wqv was published on March 4, 2025 and was last updated on March 11, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
