1) Missing Authentication for Critical Function (CVE-ID: CVE-2026-27446)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to missing authentication checks within the Core protocol. A remote non-authenticated attacker can use the Core protocol to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker and inject messages into any queue and/or exfiltrate messages from any queue via the rogue broker.
