### Impact All versions of Argo CD starting with v0.5.0 are vulnerable to an information disclosure bug allowing unauthorized users to enumerate application names by inspecting API error messages. An attacker could use the discovered application names as the starting point of another attack. For example, the attacker might use their knowledge of an application name to convince an administrator to grant higher privileges (social engineering). Many Argo CD API endpoints accept an application name as the only parameter. Since Argo CD RBAC requires both the application name and its configured project name (and, if apps-in-any-namespace is enabled, the application's namespace), Argo CD fetches the requested application before performing the RBAC check. If the application does not exist, the API returns a "not found". If the application does exist, and the user does not have access, the API returns an "unauthorized" error. By trial and error, an attacker can infer which applications exist ...
