CVE-2026-73395Network attack vector

Booking tampering via unauthenticated object reference

Published Aug 18, 2026 · Updated Aug 18, 2026

Insecure direct object reference in WpDevArt Booking Calendar 3.2.36 and earlier allows remote attackers to alter booking objects. Patchstack and the CVE record do not identify the affected endpoint or parameter, only that the plugin fails to enforce authorization on object references supplied by unauthenticated requests. Exposure is limited to sites running the vulnerable WordPress plugin, and the published CVSS confines the impact to unauthorized data changes and service interruption rather than code execution.
