TL;DR: A flaw in ServiceNow’s Virtual Agent could let unauthenticated attackers execute arbitrary code, create admin accounts, and move laterally through connected systems when a universally used third-party credential and weak email-only verification are in place, according to ZioSec. The issue shows that agentic AI integrated into existing workflows without stronger identity controls turns authentication shortcuts into enterprise control-plane risk.
NHIMG editorial — based on content published by ZioSec: Critical AI Vulnerability in ServiceNow's Virtual Agent Exposed
Questions worth separating out
A: A shared credential collapses accountability and widens the blast radius.
Q: Why do email-only checks fail for AI workflows that can change enterprise state?
A: Email-only checks provide weak assurance and are easy to abuse when the resulting action is administrative.
Q: How should security teams detect abuse of an AI-supported enterprise workflow?
A: Focus on post-authentication behaviour, not just login events.
Practitioner guidance
- Eliminate shared external credentials for AI integrations Assign unique, traceable credentials to each third-party integration and revoke any universal secret that can authenticate multiple services through the same path.
- Add step-up checks before sensitive AI actions Require stronger verification before any AI workflow can create accounts, modify permissions, or touch connected systems.
- Alert on unauthorized admin creation and API anomalies Build detection for new administrative accounts, unusual API calls, and AI-initiated actions from unrecognised sources.

- The exact attack path involving the universal external credential and how it was applied to the Virtual Agent API
- The specific indicators of compromise teams should look for in logs, accounts, and API activity
- The defensive measures ZioSec lists for credential management, MFA, AI access control, and audit cadence

Shared external credentials are not just secrets, they are delegated trust without lifecycle control: A universal credential used across third-party services turns one authentication artifact into many identities with the same effective privilege. That pattern breaks the assumption that external actors can be individually governed, reviewed, and offboarded. The implication is that organisations must stop treating shared integration credentials as low-risk plumbing and recognise them as a governance failure in the access model.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- That visibility gap includes 38% with no or low visibility and a further 47% with only partial visibility, which leaves delegated access poorly governed.
A question worth separating out:
Q: Who is accountable when an AI integration is used to create administrative access?
A: Accountability sits with the teams that own the integration, the identity controls, and the downstream system it can touch. If a third-party service can create privileged accounts, then IAM, application owners, and security operations all share responsibility for the trust boundary and the resulting access decisions.
