CISA ADP Vulnrichment

Why this deserves its current priority

A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Affected scope and exposure questions

The current feed maps OCaml/cstruct (generic). Check affected ranges and fixed versions before updating.

Recommended response

1. 1Check inventory. Check lockfiles and deployed manifests for OCaml/cstruct.
2. 2Review the reported fix. Update OCaml/cstruct to 6.3.0 if you use the affected versions. Test the change in a non-production environment first.
