Summary

CVE-2026-16823 is an improper authentication vulnerability (CWE-287) in IBM Security Verify Access and IBM Verify Identity Access. A remote attacker can bypass security restrictions without privileges or user interaction. The CVSS v3.1 base score is 9.1 (Critical).

Technical details

  • Root cause: improper authentication (CWE-287) in the product’s authentication mechanisms.
  • Trigger conditions: none beyond network reachability of the affected product. No privileges and no user interaction are required, and attack complexity is low.
  • Attack vector: network.
  • Impact: high confidentiality and high integrity impact. There is no availability impact.
  • Further technical detail, such as the specific affected component or exploitation method, was not published in the CVE record.

Affected software

  • IBM Security Verify Access: 10.0 through 10.0.9.2
  • IBM Verify Identity Access: 11.0 through 11.0.3
  • IBM Security Verify Access Container: 10.0 through 10.0.9.2
  • IBM Verify Identity Access Container: 11.0 through 11.0.3

Severity

CVSS v3.1 base score: 9.1 (Critical)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Mitigation and recommended actions

  • Immediate: upgrade IBM Verify Identity Access to 11.0.3.1, or IBM Security Verify Access to 10.0.9.3. For container deployments, apply the container updates described in IBM’s advisory.
  • Follow the IBM security bulletin for the exact fix packages and installation instructions.
  • No workarounds are listed in the sources reviewed. Until patching is complete, restrict network access to the affected instances where feasible.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
