DescriptionOpenBao is an open source identity-based secrets management system. Prior to 2.6.0, OpenBao Agent's exec rendering mode could write secrets from env_template to standard output when command/agent/exec/exec.go re-created the template runner after repeated rendering failures, primarily after num_retries was reached. A process supervisor, log collector, or local user able to read that output could obtain the rendered secret values. This issue is fixed in version 2.6.0.
