What the vulnerability does
The Vagaro Booking Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘vagaro_code’ parameter in all versions up to, and including, 0.3 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.
Explanation of Vulnerability in Simple Terms
The Vagaro Booking Widget versions 0.3 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the widget. No authentication is required, and the vulnerability can affect multiple users across different sites. The scope is changed, meaning the impact extends beyond the vulnerable component itself.
What an attacker can do
Inject malicious JavaScript that runs in visitors' browsers and affects other users or sites.
Potential impact on your site
Visitors to your site could be redirected, have their session hijacked, or see malicious content injected into the booking widget.
Conditions required to exploit
Network access to the widget; no authentication or user interaction required.
