CVE-2026-35171

Arbitrary Code Execution via Malicious Logging Configuration in Kedro

State: Published
Severity: 9.8 Critical
Published: Apr 6, 2026
Updated: Apr 7, 2026
Reserved: Apr 1, 2026

Description

Kedro is a toolbox for production-ready data science. Prior to 1.3.0, Kedro allows the logging configuration file path to be set via the KEDRO_LOGGING_CONFIG environment variable and loads it without validation. The logging configuration schema supports the special () key, which enables arbitrary callable instantiation. An attacker can exploit this to execute arbitrary system commands during application startup. This is a critical remote code execution (RCE) vulnerability caused by unsafe use of logging.config.dictConfig() with user-controlled input. This vulnerability is fixed in 1.3.0.
