A flaw was found in advisor-backend. Multiple code paths within the application deserialize YAML (YAML Ain't Markup Language) with an unsafe full Loader, which can instantiate arbitrary Python objects via YAML tags. An unauthenticated remote attacker can exploit this by submitting specially crafted YAML input, leading to remote code execution (RCE) within the `advisor-backend` pod. This compromise could allow access to shared database credentials and impact all tenants.
