Authenticated data compromise via inadequate cryptographic validation
Published Aug 12, 2026 · Updated Aug 12, 2026
Cryptographic validation weakness in IBM Verify Identity Access 11.0 through 11.0.3 allows remote authenticated users to read or alter data. In certain Reverse Proxy configurations, cryptographic checks accept user-supplied data under weaker validation, but IBM has not disclosed the algorithm, parser, or verification routine. Exploitation requires low-privileged authentication and high-complexity conditions; the documented consequence is limited to data confidentiality and integrity, with no service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0 <=10.0.9.2
- Affected versionversion=11.0 <=11.0.3
