TL;DR: Privilege escalation remains a core IAM failure mode because a compromised low-privilege account can cross boundaries it should never reach, and Soffid cites Microsoft data showing this category accounted for 40% of the vulnerabilities studied, while NHIMG reports 97% of NHIs have excessive privileges. IAM strategy breaks when privilege boundaries exist in policy but not in practice.
Editorial analysis by NHI Mgmt Group, based on content published by Soffid: “Privilege Escalation: The Invisible Risk in Your IAM Strategy”.
By the numbers:
- Privilege escalation accounted for 40% of the vulnerabilities studied in the 2026 Microsoft Vulnerabilities Report, according to Soffid.
Key questions
Q: What breaks when least privilege is missing?
A: When least privilege is missing, a single compromised identity can reach far more systems and data than the task requires.
Q: Why do excessive privileges create so much access risk?
A: Excessive privileges increase risk because any compromised or misused account can reach more systems, data, and workflows than it should.
Q: How can security teams measure whether local privilege escalation risk is actually controlled?
A: Track whether any privileged process executes from user-modifiable directories, whether ACLs on management paths are restrictive, and whether detections exist for script or DLL replacement between validation and load.
Practitioner guidance
- Audit indirect privilege paths Review group nesting, inherited roles, and chained entitlements that let a low-privilege identity reach critical systems without a direct grant.
- Rebaseline non-human identity privileges Reduce default access for service accounts, tokens, and workload identities so each one is limited to the minimum task scope.
- Harden privileged account controls Separate privileged workflows from ordinary access, and require stronger controls where escalation would expose administrative or sensitive functions.
Bottom line: Privilege escalation in IAM is a control failure that lets a compromised identity move beyond its intended authority.

Privilege escalation is an IAM boundary failure, not just an attack technique. Once a low-privilege account can move beyond its intended scope, policy has stopped matching reality. That gap matters equally for human and non-human identities, because the control failure is the same: access exists where business need does not. Practitioners should treat privilege boundaries as an enforcement problem, not a documentation exercise.
A few things that frame the scale:
- 83% of privilege escalation incidents involved no CVE exploitation, according to Verizon's 2026 Data Breach Investigations Report.
A question worth separating out:
Q: How should organisations govern non-human identities that accumulate excess access?
A: Treat service accounts, API keys and automation tokens like privileged identities, not background plumbing. Inventory them, assign ownership, set expiry rules where possible, and revoke rights when the workload changes. NHI governance breaks down when machine access is outside the normal review and offboarding process.
