+  "summary": "Kedro has Arbitrary Code Execution via Malicious Logging Configuration",
+  "details": "### Impact\n\nThis is a **critical Remote Code Execution (RCE)** vulnerability caused by unsafe use of `logging.config.dictConfig()` with user-controlled input.\n\nKedro 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.\n\n---\n\n### Patches\n\nThe vulnerability is fixed by introducing validation that rejects the unsafe `()` factory key in logging configurations before passing them to `dictConfig()`.\n\n#### Fixed in\n- Kedro 1.3.0\n\nUsers should upgrade to this version as soon as possible.\n\n---\n\n### Workarounds\n\nIf upgrading is not immediately possible:\n\n- Do not allow untrusted input to control the `KEDRO_LOGGING_CONFIG` environment variable  \n- Restrict write access to logging configuration files  \n- Avoid using externally supplied or dynamically generated logging configs  \n- Manually validate logging YAML to ensure it does not contain the `()` key  \n\nThese mitigations reduce risk but do not fully eliminate it.",
