CVE-2026-72575
daptin - Authentication Bypass via Null Owner Permission Check on usergroup Objects
CVSS Score
9.1
EPSS Score
0.0%
EPSS Percentile
0th
An improper authorization vulnerability in daptin through v0.12.34 allows unauthenticated remote attackers to read, create, update, and delete usergroup records. The permission check functions (CanRead, CanPeek, CanCreate, CanUpdate, CanDelete, CanRefer) in server/permission/permission.go return true whenever p.UserId equals the requesting userId, but fail to reject the null/zero reference — unlike CanExecute, which explicitly guards it.
