Summary

CVE-2026-13016 is an unauthenticated SQL injection vulnerability (CWE-89) in the ServiceNow AI Platform. It allows an unauthenticated attacker to execute arbitrary SQL statements against the underlying instance database, potentially gaining access to or modifying data beyond what was intended. The flaw is rated CRITICAL with a CVSS score of 9.3.

Technical details

  • Root cause: Improper neutralization of special elements used in SQL commands (CWE-89) within the ServiceNow AI Platform, allowing untrusted input to be incorporated into SQL statements without adequate sanitization.
  • Trigger conditions: ServiceNow states the flaw is exploitable "in certain circumstances" by an unauthenticated user; no additional detail on the specific endpoint or trigger has been disclosed publicly.
  • Attack vector: Network-based, requiring no authentication, no privileges, and no user interaction (AV:N/AC:L/AT:N/PR:N/UI:N).
  • Impact: Full compromise of confidentiality, integrity, and availability of instance data — an attacker can read, modify, or otherwise manipulate data stored in the underlying database beyond intended access boundaries.
  • ServiceNow states it is not currently aware of any malicious exploitation of this vulnerability against its instances.

Affected software

ServiceNow AI Platform releases prior to the following patched versions:

  • Yokohama — before Patch 13 Hot Fix 5a
  • Zurich — before Patch 10 Hot Fix 3b
  • Zurich — before Patch 10 Hot Fix 4a W32
  • Zurich — before Patch 11 Hot Fix 3
  • Australia — before Patch 2 Hot Fix 4b W32
  • Australia — before Patch 4 Hot Fix 3
  • Australia — before Patch 5

Severity

  • CVSS v4.0 Base Score: 9.3 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade to the patched release for your track — Yokohama Patch 13 Hot Fix 5a or later; Zurich Patch 10 Hot Fix 3b / Hot Fix 4a W32 or Patch 11 Hot Fix 3 or later; Australia Patch 2 Hot Fix 4b W32, Patch 4 Hot Fix 3, or Patch 5 or later. ServiceNow has already deployed the update to hosted instances; self-hosted and partner-hosted customers should apply the update as soon as possible.
  • If unable to patch immediately: Consult the official ServiceNow security advisory (KB3159623) for any interim guidance, and restrict/monitor unauthenticated network access to the AI Platform components until the patch is applied.

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.
