CVE-2026-5926Network attack vector

Sensitive-data decryption via weak cryptographic algorithms

Published Apr 22, 2026 · Updated Apr 22, 2026

Weak cryptography in IBM Verify Access products 10.0 through 11.0.2 allows remote authenticated users to decrypt sensitive information. IBM has not disclosed the affected cryptographic component, algorithm, key material, or operation that applies the weaker-than-expected primitive. Network access with low privileges is required, and the published impact is limited to disclosure of highly sensitive information without integrity or availability effects.
