CVE-2026-76376: Information Disclosure through Action Parameters in AWS IAM app for Splunk SOAR
In versions below 2.1.9 of the AWS IAM app for Splunk SOAR, a user who holds a role with permission to run actions could expose sensitive AWS credentials by invoking an action that accepts the credentials parameter, because the parameter is not masked and is shown in cleartext in the user interface. The information disclosure is possible because the app does not mark the affected action parameter as a password.
