CVE-2026-76595

advisor-backend: Unsafe YAML deserialization of associate-editable Task playbook (yaml.Loader)

In the Trivy database since at least 24 Oct 2026, 07:11 UTCWhen it arrived before that build is not recorded.

Severity by source

No source gives a CVSS score.

Trivy's own label is CRITICAL. Rated critical by Red Hat.

Description

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.
