CVE-2026-40315

Full vulnerability record from the local CVENow database.

Description

PraisonAI is a multi-agent teams system. Prior to 4.5.133, there is an SQL identifier injection vulnerability in SQLiteConversationStore where the table_prefix configuration value is directly concatenated into SQL queries via f-strings without any validation or sanitization. Since SQL identifiers cannot be safely parameterized, an attacker who controls the table_prefix value (e.g., through from_yaml or from_dict configuration input) can inject arbitrary SQL fragments that alter query structure. This enables unauthorized data access, such as reading internal SQLite tables like sqlite_master, and manipulation of query results through techniques like UNION-based injection. The vulnerability propagates from configuration input in config.py, through factory.py, to the SQL query construction in sqlite.py. Exploitation requires the ability to influence configuration input, and successful exploitation leads to internal schema disclosure and full query result tampering. This issue has been fixed in version 4.5.133.

      "value": "PraisonAI es un sistema de equipos multiagente. Antes de la 4.5.133, existe una vulnerabilidad de inyección de identificadores SQL en SQLiteConversationStore donde el valor de configuración table_prefix se concatena directamente en las consultas SQL a través de f-strings sin ninguna validación o saneamiento. Dado que los identificadores SQL no pueden ser parametrizados de forma segura, un atacante que controla el valor table_prefix (por ejemplo, a través de la entrada de configuración from_yaml o from_dict) puede inyectar fragmentos SQL arbitrarios que alteran la estructura de la consulta. Esto permite el acceso no autorizado a datos, como la lectura de tablas internas de SQLite como sqlite_master, y la manipulación de los resultados de las consultas a través de técnicas como la inyección basada en UNION. La vulnerabilidad se propaga desde la entrada de configuración en config.py, a través de factory.py, hasta la construcción de la consulta SQL en sqlite.py. La explotación requiere la capacidad de influir en la entrada de configuración, y una explotación exitosa conduce a la divulgación del esquema interno y la manipulación completa de los resultados de la consulta. Este problema ha sido solucionado en la versión 4.5.133."
