The Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via settings in all versions up to, and including, 10.14.1 due to insufficient input sanitization and output escaping.

AI Analysis
Technical Summary
The Booking Calendar WordPress plugin (versions up to 10.14.1) contains a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated attackers with Administrator privileges can inject arbitrary web scripts via plugin settings, which execute when other users view the affected pages. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No patch or vendor advisory details are provided, and no known exploits have been reported.
Potential Impact
Successful exploitation allows an authenticated administrator-level user to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to partial confidentiality and integrity compromise, such as session hijacking or unauthorized actions performed on behalf of users. Availability is not impacted. There are no known exploits in the wild, and no official patch information is currently available.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrator-level access to trusted users only and monitor for suspicious activity related to the Booking Calendar plugin settings. Avoid visiting or sharing pages that may contain injected scripts. Follow vendor communications for updates on patches or mitigations.
