The TillKit WordPress plugin before 1.0.5 does not require the hard-coded, publicly known PIN of the privileged POS account it creates on activation to be changed before use, and it authenticates its public POS login endpoint on that PIN alone with no identity or capability check, allowing unauthenticated attackers to obtain a privileged POS session and thereby read customer and site-user personal data and modify store data.
