CVE-2026-16282: CWE-287 Improper Authentication in Appointment Hour Booking
The Appointment Hour Booking WordPress plugin before 1.5.88 does not validate a client-supplied booking price against the server-side configured service price, allowing unauthenticated users to submit an arbitrary final price (including zero or negative) that is stored as the authoritative booking price, corrupting booking and payment records.
AI Analysis
Technical Summary
CVE-2026-16282 is an improper authentication vulnerability (CWE-287) in the Appointment Hour Booking WordPress plugin prior to version 1.5.88. The plugin does not verify that the booking price submitted by a client matches the server-side configured service price. As a result, unauthenticated users can manipulate the final booking price to arbitrary values, including zero or negative amounts. This flaw leads to corrupted booking and payment data, potentially impacting the integrity of financial transactions and records within the plugin.
Potential Impact
Unauthenticated attackers can submit arbitrary booking prices, including zero or negative values, which corrupts booking and payment records. This undermines the integrity of the booking system's financial data and could lead to financial loss or accounting discrepancies for the affected site owners.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, users should consider disabling the plugin or restricting access to booking functionality to trusted users only.
