CVE-2026-16797Network attack vector

Authenticated option disclosure via user-controlled optionSection key

Published Jul 28, 2026 · Updated Jul 28, 2026

Authorization bypass in ShopLentor 3.4.5 and earlier allows remote authenticated users to read selected WordPress option values. The Flash Sale countdown block API accepts optionSection as a wp_options key and retrieves that option without restricting the requested key. Contributor-level access is required, and disclosure is limited to array-of-arrays values containing title keys, enabling cross-plugin configuration leakage.
