AI Analysis

Impact

The vulnerability is a missing authorization flaw that enables an attacker to access booking features or data without the proper permissions. This broken access control can allow an unauthorized user to view, modify, or delete booking information, placing the confidentiality and integrity of appointment data at risk. The weakness corresponds to CWE-862, a classic authority‑check failure.

Affected Systems

Webba Appointment Booking, version 6.2.1 or earlier, includes the webba-booking-lite plugin bundled with WordPress sites.

Risk and Exploitability

The CVSS score of 4.3 indicates a moderate impact when a proper authenticated privilege is absent. The EPSS score of less than 1% suggests that exploitation is unlikely but not impossible. The vulnerability is not listed in CISA’s KEV catalog, and no official patch or workaround has been provided by the vendor. The attack vector is inferred to be local or web‑based, exploiting administrative or user controls left improperly configured.
