description

loopx versions 0.0.1 through 0.4.4 expose unauthenticated serve-status responses to cross-origin reads. An attacker can obtain control-plane and goal-related information, including local paths and Markdown content under registered goal roots, if an operator visits attacker-controlled web content while the local service is reachable.

mitigation

Upgrade loopx to version 0.4.5 or later. Until upgraded, avoid running serve-status when browsing untrusted websites and restrict access to the local service.

fixed in 0.4.5
