What is CVE-2026-107126?

The WP Booking System plugin for WordPress, prior to version 2.1.0.1, fails to properly sanitize user input before storing and subsequently displaying it on the admin interface. This oversight allows attackers to inject malicious scripts, leading to Stored Cross-Site Scripting (XSS) attacks. An unauthenticated attacker could exploit this vulnerability to execute arbitrary scripts in the context of an administrator's session when they access the affected stored data, potentially compromising the site's security.

Affected Version(s)

WP Booking System 0 < 2.1.0.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
