Executive Summary

This vulnerability is a Cross-site Scripting (XSS) issue found in the Bookly plugin, specifically in the bookly-responsive-appointment-booking-tool. It occurs due to improper neutralization of input during web page generation, which allows an attacker to inject malicious scripts that are reflected back to users.

Detection Guidance

This vulnerability is a reflected Cross Site Scripting (XSS) issue in the Bookly WordPress plugin (versions up to 26.7). Detection typically involves identifying malicious script injections in web requests or responses related to the plugin.

While no specific commands are provided, common detection methods include monitoring HTTP requests for suspicious input parameters that reflect back in responses without proper sanitization, and using web vulnerability scanners that test for reflected XSS vulnerabilities on pages served by the Bookly plugin.

Additionally, enabling Patchstack’s automatic mitigation rule can help block attacks targeting this vulnerability until the plugin is updated.

Mitigation Strategies

The immediate and recommended step to mitigate this vulnerability is to update the Bookly WordPress plugin to version 26.8 or later, where the issue has been patched.

Until the update can be applied, users are advised to enable Patchstack’s automatic mitigation rule, which blocks attacks targeting this specific vulnerability.

Additionally, limiting user interaction with untrusted links or pages that could exploit this reflected XSS vulnerability can reduce risk.
