FKIE_CVE-2026-1929

Vulnerability from fkie_nvd - Published: 2026-02-25 09:16 - Updated: 2026-04-15 00:35
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
