CVE-2026-16797

ShopLentor <= 3.4.5 - Insecure Direct Object Reference to Authenticated (Contributor+) Sensitive Information Exposure via 'optionSection' Parameter

The ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.4.5 via the 'optionSection' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to read arbitrary wp_options rows — including internal plugin news feed data, WooCommerce block pattern transients, and third-party configuration records — whose values are stored as arrays-of-arrays containing 'title' keys, enabling cross-plugin data leakage.
