CVE-2026-23843Network attack vector

Cross-account offer disclosure via missing ownership check

Published Jan 19, 2026 · Updated Jan 19, 2026

IDOR in teklifolustur_app allows remote authenticated users to read other users' offers through a manipulated offer_id parameter. In view_offer.php, the lookup selects an offer by the user-controlled id value and returns its details without comparing the offer's user_id with the authenticated session's user_id. Any authenticated account can enumerate another user's offer identifier and obtain that offer and its associated items; no user interaction is required.
