AI-suggested

Users should ensure that all previously released errata relevant to their system are applied before upgrading. If the cert-manager Operator's approval policy is set to 'Automatic' (the default), the upgrade to a fixed version will occur automatically with no user action required. If the approval policy is set to 'Manual', users must manually approve the upgrade. Refer to the official Red Hat documentation at https://docs.openshift.com/container-platform/latest/security/cert_manager_operator/index.html for detailed upgrade instructions.

Description

A security advisory has been issued for version 1.18.2 of this operator. The advisory highlights a high-severity vulnerability identified as CVE-2024-34459. The operator can be upgraded automatically if the installation uses the default automatic approval policy, or manually if set otherwise.
