FKIE_CVE-2026-2893

Vulnerability from fkie_nvd - Published: 2026-03-05 08:15 - Updated: 2026-04-22 21:27
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
The Page and Post Clone plugin for WordPress is vulnerable to SQL Injection via the 'meta_key' parameter in the content_clone() function in all versions up to, and including, 6.3. This is due to insufficient escaping on the user-supplied meta_key value and insufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection is second-order: the malicious payload is stored as a post meta key and executed when the post is cloned.

Esto se debe a un escape insuficiente del valor \u0027meta_key\u0027 proporcionado por el usuario y a una preparaci\u00f3n insuficiente en la consulta SQL existente. Esto permite a atacantes autenticados, con acceso de nivel Colaborador o superior, a\u00f1adir consultas SQL adicionales a consultas ya existentes que pueden usarse para extraer informaci\u00f3n sensible de la base de datos. La inyecci\u00f3n es de segundo orden: la carga \u00fatil maliciosa se almacena como una clave meta de publicaci\u00f3n y se ejecuta cuando se clona la publicaci\u00f3n."
