CVE-2026-72575 · Severity: critical · CVSS 9.1 · Published 2026-08-10

Daptin is a self-hosted API and data management platform. An improper authorization flaw in versions through 0.12.34 allows unauthenticated attackers to read, create, modify, and delete sensitive usergroup data without any credentials. This could lead to unauthorized access to user management controls and complete compromise of application security governance.

## Technical details

The vulnerability is an improper authorization flaw in daptin's permission checking logic (server/permission/permission.go). The CanRead, CanPeek, CanCreate, CanUpdate, CanDelete, and CanRefer functions return true when the permission's UserId matches the requesting UserId, but fail to reject null or zero references — a check that the CanExecute function correctly performs. This allows unauthenticated remote attackers to bypass authorization and manipulate usergroup records. The attack requires network access to the daptin instance but no authentication or user interaction. A patch has been made available; administrators should upgrade to a version after 0.12.34.
