CVE-2026-0770

The vulnerability results from improper handling of the exec_globals parameter passed to the validate endpoint. The application includes resources from an untrusted sphere of control (CWE-829), which allows an attacker to inject and execute malicious code. The exploit requires no authentication or user interaction — it is sufficient to send an appropriately crafted network request.

An attacker can execute arbitrary code in the context of the root user, which means complete takeover of the compromised system, including access to data, ability to install backdoors, and further lateral movement within the network.

Patches available from the vendor should be applied according to the references. Additionally, until the patch is deployed, it is recommended to restrict network access to the validate endpoint using firewall or access control mechanisms.
