The vulnerability does not lead to denial of service or remote code execution but can expose all data that the workflow application can access.

The vulnerability is not listed in CISA\u2019s KEV catalog, meaning it has not yet been confirmed in publicly known exploits. The likely attack path requires an attacker with elevated (high) privileges and network access to the HTTP interface of the Workflow Loader.
