Analyze CVE-2026-78401 with Vani AIImpact, affected versions, exploitation status, mitigations and detection

IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 deserialize untrusted data (CWE-502). A remote attacker who can reach the system can trigger that flaw without authentication or user interaction. Successful exploitation yields arbitrary code execution with high impact to confidentiality, integrity, and availability (CVSS 3.1 9.8). Affected systems are deployments of those IBM identity-access products in the stated version ranges. It is not listed in CISA KEV and no public proof-of-concept is known.

What to do: Upgrade IBM Security Verify Access and IBM Verify Identity Access off the affected ranges (10.0 through 10.0.9.2 and 11.0 through 11.0.3) using the vendor fix for CVE-2026-78401. Until patched, do not expose the product to untrusted networks and restrict access to trusted management hosts only.
