What is CVE-2026-1929?
CVE-2026-1929 is a high-severity code injection vulnerability in mihail-barinov Advanced Woo Labels – Product Labels & Badges for WooCommerce, published on 25 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
