## Technical details

The vulnerability is an improper certificate validation flaw affecting multiple microservices in LXCO 2.2.0. The root cause involves insufficient validation of TLS certificates during HTTPS connections, which an adjacent network attacker can exploit to perform a man-in-the-middle attack. The attack requires the attacker to be on the same network segment or adjacent network and does not require prior authentication. Successful exploitation allows interception and potential modification of encrypted management traffic. Patches or mitigations were available as of the publication date (August 2026).
