CVE-2026-48078Public exploitNetwork attack vector

Unauthenticated private-channel disclosure via missing visibility filter

Published Aug 6, 2026 · Updated Aug 6, 2026

Information disclosure in OpenReception before 1.0.5 allows remote attackers to read private channel metadata through the public schedule API. The schedule GET handler serializes every unarchived, unpaused channel without filtering on isPublic, including agent associations and computed availability. No authentication or user interaction is required, but a tenant identifier and an existing private channel are needed to expose internal service and staffing details.
