Who should care

Defenders responsible for IBM Security Verify Access and IBM Verify Identity Access systems, including administrators and security teams, should assess exposure and prioritize remediation.

Why it matters

CVE-2026-78406 is a critical remote code execution vulnerability in IBM Security Verify Access and IBM Verify Identity Access, requiring immediate attention from defenders to assess exposure and prioritize remediation.

  • Remote code execution requires immediate attention
  • Exposure of sensitive data and systems is possible
  • System compromise could lead to further attacks
  • Verification of system inventory and patching is necessary

Technical summary

IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 are vulnerable to remote code execution due to insecure deserialization of untrusted data. This vulnerability requires immediate attention from defenders to assess exposure and prioritize remediation. The deserialization vulnerability could allow a remote unauthenticated attacker to execute arbitrary code on the system, potentially leading to system compromise and data exposure.

Defensive priority

High
