CVE-2025-36041

Sensitive-data disclosure via unintended CRR certificate chain

Published Jun 15, 2025 · Updated Aug 24, 2025

Improper certificate validation in affected IBM MQ Operator releases allows local users to disclose data or perform unauthorized actions. Native HA CRR certificate handling accepts a configured private key and certificate chain without confirming that they are the intended credentials. Exploitation requires local high-privilege access and high-complexity conditions; successful substitution exposes sensitive information or enables unauthorized actions.
