IBM Security Verify Identity Access Reverse Proxy in versions 10.0.0 and 11.0.0 has a vulnerability where cryptographic validation of user-supplied data may be weaker than intended under certain configurations. This weakness could allow attackers to bypass or weaken security controls dependent on cryptographic validation. The vulnerability is published as CVE-2026-11929. No further technical details, CVSS score, or exploit information is available at this time.

The vulnerability may reduce the effectiveness of cryptographic validation in the affected IBM Verify Identity Access Reverse Proxy versions, potentially allowing attackers to manipulate or bypass security checks that rely on this validation. However, no known exploits or active attacks have been reported, and the exact impact depends on the specific configuration and usage of the product.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix or mitigation is provided by IBM, users should review their configurations for cryptographic validation settings and consider applying any recommended security best practices from IBM.
