| Doc Text: |
A flaw was found in advisor-backend. A network-adjacent unauthenticated attacker could exploit a vulnerability in the `/private/import_content/` endpoint, which lacks proper authentication and permission checks. This allows the attacker to overwrite the global Advisor rule, resolution, and playbook catalogue. When combined with another vulnerability involving unsafe YAML deserialization, this could lead to arbitrary code execution on affected systems.
