CVE-2026-76635
baserCMS < 5.3.0 SQL Injection and Code Injection via BcDatabaseService.php
Description
baserCMS before 5.3.0 contains a SQL injection vulnerability in BcDatabaseService.php that allows authenticated administrators to inject attacker-controlled table names and configuration values directly into SQL statements across sequence update, CSV export, and table management operations. Attackers can chain a backup restore code injection flaw, where PHP code outside class definitions in schema files executes unconditionally upon loading, to plant malicious table names and trigger error-based SQL injection that retrieves database version, schema contents, and arbitrary data from the PostgreSQL backend.

Action Type Old Value New Value Added Translation Title: basercms de baserproject, Description: baserCMS antes de 5.3.0 contiene una vulnerabilidad de inyección SQL en BcDatabaseService.php que permite a los administradores autenticados inyectar nombres de tabla y valores de configuración controlados por el atacante directamente en sentencias SQL a través de operaciones de actualización de secuencia, exportación CSV y gestión de tablas. Los atacantes pueden encadenar un fallo de inyección de código en la restauración de copias de seguridad, donde el código PHP fuera de las definiciones de clase en los archivos de esquema se ejecuta incondicionalmente al cargarse, para insertar nombres de tabla maliciosos y desencadenar una inyección SQL basada en errores que recupera la versión de la base de datos, el contenido del esquema y datos arbitrarios del backend de PostgreSQL. -
