CVE-2025-69007 identifies a stored Cross-Site Scripting (XSS) vulnerability in the OTWthemes Popping Sidebars and Widgets Light WordPress plugin, versions up to and including 1.27. The vulnerability stems from improper neutralization of input during the generation of web pages, which allows an authenticated attacker to inject malicious scripts that are stored and later executed in the context of users visiting the affected site. The CVSS 3.1 score is 5.9 (medium), reflecting that exploitation requires network access, low attack complexity, but demands privileges (authenticated user) and user interaction (victim must trigger the malicious script). The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as injected scripts can steal session tokens, manipulate content, or perform actions on behalf of users. No public exploits have been reported yet, but the stored nature of the XSS increases the risk of persistent attacks. The plugin is commonly used in WordPress environments to manage sidebars and widgets, making it a relevant target for attackers seeking to compromise websites that rely on this plugin for UI enhancements. The vulnerability was published on December 30, 2025, by Patchstack and remains unpatched at the time of reporting.

For European organizations, this vulnerability could lead to unauthorized access to user sessions, data leakage, and potential defacement or manipulation of website content. Organizations handling sensitive customer data or financial transactions through WordPress sites using this plugin are at heightened risk. Attackers could leverage the stored XSS to perform phishing, spread malware, or escalate privileges within the web application. The impact extends to brand reputation damage and regulatory compliance issues under GDPR if personal data is compromised. Given the requirement for authenticated access, internal users or compromised accounts could be initial vectors, emphasizing insider threat risks. The availability of the plugin across many European WordPress sites, especially in e-commerce, media, and public sector websites, increases the potential attack surface.

1. Monitor for and apply security patches from OTWthemes as soon as they are released to address this vulnerability. 2. Until patches are available, consider disabling or removing the Popping Sidebars and Widgets Light plugin from production environments. 3. Implement strict input validation and sanitization on all user inputs, especially those that affect sidebar and widget content. 4. Deploy Content Security Policy (CSP) headers to restrict execution of unauthorized scripts. 5. Enforce least privilege principles for user accounts to limit authenticated access to trusted users only. 6. Conduct regular security audits and penetration testing focused on XSS vulnerabilities in WordPress plugins. 7. Educate users and administrators about the risks of stored XSS and safe handling of plugin configurations. 8. Utilize Web Application Firewalls (WAF) with rules designed to detect and block XSS payloads targeting this plugin.
