CVE-2026-11929 describes a cryptographic validation weakness in IBM Security Verify Identity Access Reverse Proxy under certain configurations. The flaw involves weaker than expected cryptographic validation of user-supplied data, potentially undermining the integrity of the validation process. The CVSS 3.1 score is 7.5, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and confidentiality impact only. No known exploits are reported in the wild. No patch or remediation information is currently available.

The vulnerability could allow an attacker to bypass cryptographic validation mechanisms, potentially exposing sensitive data or allowing unauthorized access. The impact is limited to confidentiality compromise; integrity and availability are not affected according to the CVSS vector. No active exploitation is known at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until official fixes or mitigations are published by IBM, users should review their configurations to ensure cryptographic validation settings are as strong as possible and monitor IBM advisories for updates.
