Odoo Permission Audit: Finding Over-Privileged Users Before They Cause Damage
Over-privileged users are the most common security gap in Odoo installations. Learn how to audit access groups, detect admin sprawl, and enforce least-privilege.
In every Odoo security audit we've conducted, the single most common finding is over-privileged users. It's not malicious — it's organic. A support request comes in, someone gets elevated access to fix it, and the elevation is never reverted. Multiply this by years of operation and dozens of employees, and you have a permission landscape that no one fully understands.
The Real Risk of Admin Sprawl
Every user with administrative access is a potential vector for:
- Data exfiltration — Admin users can export any record from any model
- Configuration damage — One wrong setting change can break workflows for the entire organization
- Audit trail gaps — When everyone is admin, the audit trail becomes meaningless because you can't distinguish authorized changes from unauthorized ones
- Compliance violations — SOC 2, GDPR, and ISO 27001 all require least-privilege access controls
Common Permission Anti-Patterns
1. The "Technical Features" Overload
The "Technical Features" access group in Odoo gives users access to developer tools, database structure, and advanced settings. In many organizations, 30-50% of users have this group enabled — far more than need it. Only system administrators and technical leads should have this access.

2. Shared Admin Accounts
Multiple people logging in with the same admin account is still shockingly common. This destroys individual accountability and makes it impossible to trace who made what change.
3. Deactivated Employees with Active Accounts
When an employee leaves, their Odoo account should be deactivated immediately. In practice, orphaned accounts are one of the most common findings in Odoo health scans — some belonging to employees who left years ago.
4. External Users with Internal Groups
Portal users sometimes get assigned to internal access groups during troubleshooting. This can inadvertently expose internal data — invoices, purchase orders, HR records — to external parties.
How to Run a Permission Audit
A thorough permission audit involves:
- Export all users and their groups — Use
res.usersandres.groupsto build a complete access matrix - Identify elevated accounts — Flag any user with admin, technical features, or settings access
- Cross-reference with HR — Match active accounts against your current employee roster
- Check record rules — Verify that record-level security rules haven't been weakened or removed
- Review API access — Any user with XML-RPC access is a potential attack surface
NonaGuard automates this entire process. Our permission scanner maps every user to every access group, flags admin sprawl, detects orphaned accounts, and identifies external users with internal access — all in a single scan.
