CVE-2026-72575daptin - Authentication Bypass via Null Owner Permission Check on usergroup Objects

Updated under an hour ago ()

Does this affect you?

It affects daptin. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
