CVE-2026-1929

high

Description

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.
