CVE-2025-69350 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the Themepoints Accordion WordPress plugin, affecting versions up to and including 3.0.3. The root cause is 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 plugin’s data structures. When a victim user accesses a page containing the malicious payload, the script executes in their browser context, potentially leading to session hijacking, defacement, or redirection to malicious sites. The vulnerability requires the attacker to have at least low privileges (PR:L), such as a contributor or subscriber role, and also requires user interaction (UI:R) for the payload to execute. The attack vector is network-based (AV:N), meaning exploitation can be performed remotely over the internet. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L), and the scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. Although no known exploits are currently reported in the wild, the widespread use of WordPress and the popularity of the Themepoints Accordion plugin increase the risk of exploitation once a public exploit becomes available. The lack of an official patch link suggests that remediation may require manual intervention or monitoring for updates from the vendor. The vulnerability was published on January 6, 2026, and was reserved on December 31, 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a moderate risk primarily to websites and web applications utilizing the Themepoints Accordion plugin. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, theft of sensitive information, unauthorized actions on behalf of users, or defacement of public-facing content. This can damage organizational reputation, lead to data breaches, and disrupt business operations. Given the plugin’s integration with WordPress, a widely used CMS in Europe, the attack surface is significant. Organizations in sectors with high web presence, such as e-commerce, media, and government services, are particularly at risk. The requirement for low privileges and user interaction somewhat limits the ease of exploitation but does not eliminate the threat, especially in environments with many users or contributors. The vulnerability could also be leveraged as part of a multi-stage attack chain, increasing its potential impact. Additionally, compliance with GDPR and other data protection regulations means that exploitation leading to data leakage could result in legal and financial penalties.

European organizations should take the following specific actions to mitigate this vulnerability: 1) Monitor Themepoints and WordPress security advisories closely and apply official patches or updates to the Accordion plugin immediately upon release. 2) In the absence of a patch, consider temporarily disabling or removing the Accordion plugin from production environments to eliminate exposure. 3) Implement strict input validation and output encoding on all user-supplied data within the plugin’s scope, potentially through custom code or security plugins that sanitize inputs. 4) Deploy Web Application Firewalls (WAFs) configured to detect and block common XSS payloads targeting WordPress plugins. 5) Conduct regular security audits and penetration testing focusing on web application vulnerabilities, including stored XSS. 6) Educate content contributors and administrators about the risks of XSS and safe content management practices to reduce the likelihood of malicious input. 7) Restrict user privileges to the minimum necessary, limiting the number of users who can submit content that is rendered by the Accordion plugin. 8) Enable Content Security Policy (CSP) headers to reduce the impact of any injected scripts by restricting script sources. These measures combined will reduce the risk of exploitation and limit potential damage.
