CVE-2025-69350 is a stored Cross-site Scripting (XSS) vulnerability identified in the Themepoints Accordion WordPress plugin, affecting all versions up to and including 3.0.3. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code that is stored persistently within the application. When other users or administrators view the affected pages, the malicious script executes in their browsers under the context of the vulnerable site. This can lead to a range of attacks including session hijacking, unauthorized actions on behalf of users, defacement, or distribution of malware. The vulnerability does not require authentication, increasing its risk profile, and no user interaction beyond visiting a compromised page is necessary for exploitation. Although no public exploits are currently known, the widespread use of WordPress and the popularity of the Themepoints Accordion plugin make this a significant threat. The lack of an official patch at the time of publication means that affected sites remain vulnerable. The vulnerability was reserved at the end of 2025 and published in early 2026, indicating recent discovery and disclosure. The absence of a CVSS score necessitates a severity assessment based on impact and exploitability factors.

For European organizations, the impact of this stored XSS vulnerability can be substantial. Many European businesses rely on WordPress for their web presence, including e-commerce, media, and governmental sites. Exploitation could lead to theft of user credentials, unauthorized administrative actions, and damage to brand reputation through defacement or malware distribution. Confidentiality of user data and integrity of website content are at risk, potentially violating GDPR requirements and leading to regulatory penalties. The availability of the site could also be indirectly affected if attackers leverage the vulnerability to inject disruptive scripts or conduct further attacks. Organizations with high web traffic or those handling sensitive user information are particularly vulnerable. The threat is amplified in countries with high WordPress market penetration and active cybercriminal communities targeting web applications.

Immediate mitigation should focus on identifying all instances of the Themepoints Accordion plugin within organizational WordPress deployments. Until an official patch is released, administrators should disable or remove the plugin to eliminate the attack surface. If removal is not feasible, implement strict input validation and output encoding on all user-supplied data related to the plugin's functionality. Employ Web Application Firewalls (WAFs) with rules designed to detect and block typical XSS payloads targeting this plugin. Regularly monitor web server logs and user activity for signs of exploitation attempts, such as unusual script injections or unexpected administrative actions. Educate web administrators about the risks of stored XSS and the importance of timely updates. Once a patch is available, apply it promptly and verify that the vulnerability is resolved through testing. Additionally, consider implementing Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks.
