Vulnerability from fkie_nvd - Published: 2026-01-16 17:15 - Updated: 2026-04-15 00:35
Severity ?
7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Summary
Kafka Connect BigQuery Connector is an implementation of a sink connector from Apache Kafka to Google BigQuery. Prior to 2.11.0, there is an arbitrary file read in Google BigQuery Sink connector. Aiven's Google BigQuery Kafka Connect Sink connector requires Google Cloud credential configurations for authentication to BigQuery services. During connector configuration, users can supply credential JSON files that are processed by Google authentication libraries. The service fails to validate externally-sourced credential configurations before passing them to the authentication libraries. An attacker can exploit this by providing a malicious credential configuration containing crafted credential_source.file paths or credential_source.url endpoints, resulting in arbitrary file reads or SSRF attacks.

Antes de la versi\u00f3n 2.11.0, existe una lectura arbitraria de archivos en el conector de sumidero de Google BigQuery. El conector de sumidero de Kafka Connect para Google BigQuery de Aiven requiere configuraciones de credenciales de Google Cloud para la autenticaci\u00f3n a los servicios de BigQuery. Durante la configuraci\u00f3n del conector, los usuarios pueden proporcionar archivos JSON de credenciales que son procesados por las librer\u00edas de autenticaci\u00f3n de Google. El servicio no valida las configuraciones de credenciales de origen externo antes de pasarlas a las librer\u00edas de autenticaci\u00f3n. Un atacante puede explotar esto al proporcionar una configuraci\u00f3n de credenciales maliciosa que contenga rutas credential_source.file manipuladas o puntos finales credential_source.url, lo que resulta en lecturas arbitrarias de archivos o ataques SSRF."
