- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

## Affected

- devitemsllc ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin: through 3.4.5

## Description

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.
