CVE-2024-52282: Rancher Helm Applications may have sensitive values leaked

A vulnerability has been identified within Rancher Manager whereby applications installed via Rancher Manager Apps Catalog store their Helm values directly into the Apps Custom Resource Definition, resulting in any users with GET access to it to be able to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2.

Application charts without sensitive data are not affected by this vulnerability. This vulnerability impacts any Helm applications installed on a Rancher Manager cluster, regardless of it being installed via the Marketplace or using the helm cli.
