AnalysisAIv1 – Jul 28, 2026

Information disclosure in ShopLentor WordPress plugin versions ≤3.4.5 allows authenticated attackers with contributor-level access to read arbitrary wp_options rows whose values are stored as arrays-of-arrays containing 'title' keys, leading to cross-plugin data leakage of internal plugin news feeds, WooCommerce block pattern transients, and third-party configuration records. The vulnerability exists due to missing authorization checks on the user-controlled 'optionSection' parameter in the plugin’s API, and no public exploit or active exploitation has been reported.

DescriptionCVE.org

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.
