CVE-2026-1929

Advanced Woo Labels <= 2.37 - Authenticated (Contributor+) Remote Code Execution via 'callback' Parameter

8.8 High

The Advanced Woo Labels plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.37. This is due to the use of call_user_func_array() with user-controlled callback and parameters in the get_select_option_values() AJAX handler without an allowlist of permitted callbacks or a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute arbitrary PHP functions and operating system commands on the server via the 'callback' parameter.
