CVE-2025-64275 is a stored Cross-site Scripting (XSS) vulnerability identified in the wpdevelop Booking Manager plugin, affecting versions up to and including 2.1.17. The vulnerability stems from improper neutralization of input during web page generation, which allows malicious input to be stored and later executed in the context of a victim's browser when viewing affected pages. This type of vulnerability enables attackers to inject arbitrary JavaScript code that can execute with the privileges of the affected web application user. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be launched remotely over the network with low attack complexity, requires low privileges (authenticated user), and user interaction (victim must trigger the malicious payload). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes partial loss of confidentiality, integrity, and availability, such as session hijacking, defacement, or unauthorized actions performed on behalf of users. No known public exploits have been reported yet, but the vulnerability is publicly disclosed and should be treated proactively. The plugin is commonly used in WordPress environments to manage bookings, making it a target for attackers seeking to exploit web application vulnerabilities. The lack of available patches at the time of disclosure increases the urgency for organizations to implement interim mitigations.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on the wpdevelop Booking Manager plugin to handle customer bookings and reservations. Exploitation could lead to unauthorized access to user sessions, theft of sensitive booking data, or manipulation of booking information, undermining customer trust and potentially violating data protection regulations such as GDPR. The partial compromise of confidentiality and integrity could result in data leakage or fraudulent bookings, while availability impacts could disrupt business operations. Organizations in sectors like hospitality, event management, and services that use this plugin are particularly at risk. Additionally, reputational damage and regulatory penalties could follow if personal data is exposed or manipulated. The requirement for user interaction and low privilege means attackers may target employees or customers with phishing or social engineering to trigger the exploit, increasing the attack surface.

1. Monitor wpdevelop’s official channels for patches and apply updates immediately once available to address CVE-2025-64275. 2. Implement strict input validation and sanitization on all user-supplied data before storage and output encoding when rendering data in web pages to prevent script injection. 3. Restrict user privileges in the Booking Manager plugin to the minimum necessary, limiting the ability of low-privileged users to inject malicious content. 4. Employ Content Security Policy (CSP) headers to reduce the impact of potential XSS by restricting the execution of untrusted scripts. 5. Conduct regular security audits and penetration testing focusing on web application inputs and stored content. 6. Educate users and staff about phishing and social engineering risks to reduce the likelihood of triggering stored XSS payloads. 7. Use web application firewalls (WAF) with rules tailored to detect and block XSS attack patterns targeting the Booking Manager plugin. 8. Isolate booking management systems where possible to limit lateral movement if compromise occurs.
