CVE-2026-14334: CWE-79 Cross-Site Scripting (XSS) in Booking calendar, Appointment Booking System
CVE-2026-14334 is a high-severity cross-site scripting (XSS) vulnerability in the Booking calendar, Appointment Booking System WordPress plugin. Versions from 3.2.18 through 3.2.36 improperly sanitize uploaded SVG files, allowing unauthenticated attackers to upload malicious SVGs that bypass script-stripping. This enables execution of arbitrary JavaScript in the context of an administrator reviewing the booking, potentially compromising confidentiality, integrity, and availability.
AI Analysis
Technical Summary
The Booking calendar, Appointment Booking System WordPress plugin through versions 3.2.36 does not properly sanitize uploaded SVG files. This allows unauthenticated attackers to upload SVG files that bypass the plugin's script-stripping mechanisms and execute arbitrary JavaScript when the SVG is opened. The vulnerability affects versions >=3.2.18 and <=3.2.36. The attack vector requires user interaction (an administrator opening the SVG), and the impact includes full confidentiality, integrity, and availability compromise as indicated by the CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary JavaScript in the session of an administrator who views the malicious SVG file. This can lead to full compromise of the administrator's session, including theft of credentials, manipulation of booking data, and potential site takeover. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No explicit patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should avoid opening SVG files uploaded via the Booking calendar plugin from untrusted sources.
