Description

Impact

This is a critical remote code execution (RCE) vulnerability caused by unsafe use of logging.config.dictConfig() with user-controlled input.

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.


Patches

The vulnerability is fixed by introducing validation that rejects the unsafe () factory key in logging configurations before passing them to dictConfig().

Fixed in

  • Kedro 1.3.0

Users should upgrade to this version as soon as possible.


Workarounds

If upgrading is not immediately possible:

  • Do not allow untrusted input to control the KEDRO_LOGGING_CONFIG environment variable
  • Restrict write access to logging configuration files
  • Avoid using externally supplied or dynamically generated logging configs
  • Manually validate logging YAML to ensure it does not contain the () key

These mitigations reduce risk but do not fully eliminate it.
