CVE-2026-12358Network attack vectorHinoki check available

Service interruption via insufficient request resource validation

Published Sep 15, 2026 · Updated Sep 15, 2026

Resource exhaustion in IBM Verify Identity Access and Security Verify Access allows remote attackers to interrupt affected services. IBM attributes the failure to insufficient validation of incoming request resources but has not disclosed the request-processing locus, resource type, or exhaustion path. No authentication or user interaction is required; appliance and container releases 10.0.0 through 10.0.9.2 and 11.0.0 through 11.0.3 are affected, and the documented consequence is service interruption only.
