No CVSS score has been assigned to GHSA-h588-76vg-prgj yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-h588-76vg-prgj?

GHSA-h588-76vg-prgj affects the following packages: arrow (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-h588-76vg-prgj?

Update arrow to 6.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h588-76vg-prgj is resolved across your whole dependency graph.

How do I detect GHSA-h588-76vg-prgj in my crates.io dependencies?

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

How do I mitigate GHSA-h588-76vg-prgj if there is no patch (or I can't update yet)?

Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.

Is GHSA-h588-76vg-prgj actively exploited in the wild?

No public exploit code has been indexed for GHSA-h588-76vg-prgj 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.
