Unauthenticated service interruption via infinite loop

Published Aug 12, 2026 · Updated Aug 12, 2026

Denial of service in IBM Verify Identity Access appliances and containers allows remote attackers to interrupt service over the network. IBM maps the flaw to an infinite loop but has not disclosed the affected component, crafted input, or erroneous operation that prevents loop termination. Affected releases are Security Verify Access 10.0 through 10.0.9.2 and Verify Identity Access 11.0 through 11.0.3; no authentication or user interaction is required, and the reported impact is limited to availability.
