Security readout for executives and security teams
Plain-English summary
Capgo versions before 12.128.2 can leave former super administrators with dangerous organization-wide permissions after demotion. A user who once had super_admin rights may still enumerate and bulk delete non-compliant bundles. This creates business risk around service integrity, release governance, and recovery workload.
Executive priority
Treat as a high-priority remediation if Capgo is used. The main concern is not initial compromise, but retained insider or former-admin capability to disrupt bundle management across an organization.
Technical view
The issue is an authorization flaw in Capgo RBAC handling. When a super_admin role binding is removed, org_users.user_right is not cleared, leaving access to delete_non_compliant_bundles and count_non_compliant_bundles RPCs. The CVSS 3.1 score is 8.3, with network access, low complexity, low privileges, no user interaction, and high integrity and availability impact.
Likely exposure
Organizations running Capgo before 12.128.2 are potentially exposed, especially where users have previously held super_admin access and were later demoted. Exposure depends on deployed version and user role history.
Exploitation context
Sources do not indicate CISA KEV listing or confirmed active exploitation. Exploitation requires a low-privileged authenticated user who previously held super_admin rights and retained stale permissions after demotion.
Researcher notes
Evidence points to stale authorization state in org_users.user_right after role binding deletion. Public sources name the affected RPCs and fixed-version boundary, but do not provide exploitation-in-the-wild evidence in the supplied bundle.
Mitigation direction
- Upgrade Capgo to version 12.128.2 or later, per the affected-version boundary.
- Review vendor advisory for any additional remediation or cleanup guidance.
- Audit users previously demoted from super_admin for retained elevated access.
- Restrict administrative access until version and role-state validation are complete.
Validation and detection
- Identify all Capgo deployments and confirm installed versions.
- Check whether any deployment is older than 12.128.2.
- Review role-change history for users demoted from super_admin.
- Verify demoted users no longer retain organization-wide bundle management permissions.
- Monitor logs for unusual non-compliant bundle enumeration or deletion activity.

Improper Authorization
Improper Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
