According to Kubernetes documentation and various k8s security guidelines, wildcards in resource and verb entries should be avoided:

Warning

Using wildcards in resource and verb entries could result in overly permissive access being granted to sensitive resources. For instance, if a new resource type is added, or a new subresource is added, or a new custom verb is checked, the wildcard entry automatically grants access, which may be undesirable. The principle of least privilege should be employed, using specific resources and verbs to ensure only the permissions required for the workload to function correctly are applied.

Refs:

This PR could be seen as a continuation of a previous work for hardening the RBAC: #625
It replaces * with explicit verbs and resources, according to KEDA needs.

This PR look nice, but we can revert if by mistake during the release if we copy the RBAC from KEDA repo. Could you open a PR there too, changing the RBAC? 🙏

Thank you, @JorTurFer ! I submitted the similar PR to the main KEDA repo: kedacore/keda#6129

Remove unnecessary "create" and "delete" verbs for CRs which are supposed to be
created and deleted only by a user, and not by an operator.
