What is CVE-2026-84166?

A security flaw exists in the Hotel Booking WordPress plugin versions up to 3.8, where the absence of Cross-Site Request Forgery (CSRF) protection in the administrative booking order management feature allows attackers to initiate unauthorized actions. This could enable malicious actors to manipulate booking order records by tricking a logged-in administrator into executing unnecessary requests. Such vulnerabilities pose a significant risk, making it crucial for site administrators to promptly update to secure versions and implement additional protective measures.

Affected Version(s)

Hotel Booking 0 <= 3.8

Exploit Proof of Concept (PoC)
