Who should care

Users of Kedro versions prior to 1.3.0 should be concerned about this vulnerability. This includes anyone who uses Kedro for production-ready data science, as an attacker could exploit this vulnerability to execute arbitrary system commands. Operators, platform administrators, vulnerability management teams, and security teams should review the vulnerability and take necessary actions to mitigate it.

Technical summary

The vulnerability exists because 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. This allows an attacker to execute arbitrary system commands during application startup. The vulnerability has a CVSS score of 9.8 and a severity of CRITICAL. Evidence is limited to public sources and may not reflect the full scope or impact of the vulnerability.

Defensive priority

High

Recommended defensive actions

  • Upgrade to Kedro version 1.3.0 or later
  • Validate and sanitize user-controlled input to logging configuration
  • Implement compensating controls to monitor and restrict system commands
  • Review and update logging configuration to prevent arbitrary callable instantiation
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
