Description
The WPBookit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpb_user_name' and 'wpb_user_email' parameters in all versions up to, and including, 1.0.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AI Analysis

Impact

The WPBookit plugin for WordPress contains a flaw that allows an unauthenticated attacker to store malicious JavaScript code by submitting crafted values for the wpb_user_name and wpb_user_email fields. When a visitor loads a page that displays these fields, the injected script runs in the visitor’s browser, enabling arbitrary client‑side code execution.

Affected Systems

All installations of the WPBookit plugin by iqonicdesign running version 1.0.8 or earlier are affected. The vulnerability does not apply to newer releases of the plugin.

Risk and Exploitability

The flaw has a CVSS base score of 7.2, indicating high severity. The EPSS score is less than 1 %, suggesting a low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog. The attack vector is an unauthenticated submission of crafted wpb_user_name and wpb_user_email values through the booking shortcode or related endpoint; once stored, any user who visits the affected page will trigger the injected payload.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade WPBookit to the latest released version, which corrects input sanitization and output escaping for the affected fields.
  • If an upgrade cannot be performed immediately, temporarily disable the booking shortcode or restrict its execution to trusted users by configuring WordPress or a security plugin.
  • Apply a content‑security‑policy that blocks the execution of untrusted scripts on pages that display the booking data.
