Hi @gafnit-lightspin,

Thank you for the great contributions!

We did a review of the list of proposed queries and since the comments are the same for all the queries, we summarize them here:

• Category and Severity are adequate. The list of queries belongs to the context of IAM privilege escalation, which fits inside the Access Control category. As for the Severity, regardless of their different type in the likelihood of exploitation, the outcome will be the same, privilege escalation.
• The Descriptions can be improved to also consider why such permission creates a security issue and that (in this case) it can lead to a privilege escalation. The reference [1] can help better understand and define a more suited approach.
• The Descriptions URL should point to the respective affected endpoints (the affected policy).
