Answer in brief
CVE-2026-31984 records a High severity (CVSS 7.5) vulnerability in DoS through oversized audit log entries in Guardian/CMC before 26.2.0. The current sources do not mark it as known exploited. The current feed maps Nozomi Networks/CMC (generic), Nozomi Networks/Guardian (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A denial-of-service vulnerability caused by unbounded resource allocation was discovered in the audit logging functionality, due to a missing size limit on input recorded into audit entries. An unauthenticated attacker can submit requests containing excessively large input that is recorded into audit entries, possibly exhausting the available disk space and rendering the system inoperable.
