CVE-2025-7726 is a stored Cross-Site Scripting (XSS) vulnerability affecting the The7 theme for WordPress, a popular website and eCommerce builder. This vulnerability exists in all versions up to and including 12.6.0. The root cause is improper neutralization of input during web page generation (CWE-79). Specifically, the theme’s JavaScript code reads user-supplied attributes 'title' and 'data-dt-img-description' directly using jQuery.attr(), then concatenates these values into an HTML string which is inserted into the DOM via jQuery.html() without proper escaping or filtering. This allows an authenticated attacker with Contributor-level access or higher to inject arbitrary JavaScript code that is stored persistently in the website's pages. When other users visit the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or other malicious actions. The vulnerability does not require user interaction beyond visiting the injected page and does not require higher privileges than Contributor, which is a relatively low-level role in WordPress. The CVSS v3.1 base score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, privileges required at the Contributor level, no user interaction needed, and partial impact on confidentiality and integrity but no impact on availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability affects a widely used commercial WordPress theme, making it a significant risk for websites relying on The7 for content and eCommerce functionality.

For European organizations, this vulnerability poses a moderate risk primarily to websites and online stores built using the The7 WordPress theme. Exploitation could lead to unauthorized script execution in visitors’ browsers, enabling theft of session cookies, redirection to malicious sites, or unauthorized actions performed on behalf of users. This can damage brand reputation, lead to data breaches involving customer information, and potentially violate GDPR requirements regarding data protection and breach notification. E-commerce sites are particularly at risk of losing customer trust and revenue. Since Contributor-level access is sufficient to exploit this vulnerability, insider threats or compromised contributor accounts can be leveraged by attackers. The persistent nature of the stored XSS means that malicious scripts remain active until the injected content is removed, increasing the window of exposure. The vulnerability’s impact on confidentiality and integrity, combined with the widespread use of WordPress and The7 theme in Europe, makes this a relevant threat to many SMEs and larger enterprises relying on WordPress for their web presence.

European organizations should immediately audit their WordPress installations to identify if The7 theme versions up to 12.6.0 are in use. Until an official patch is released, mitigation should include: 1) Restrict Contributor-level user permissions strictly and review contributor accounts for suspicious activity; 2) Implement Web Application Firewall (WAF) rules to detect and block suspicious payloads targeting the 'title' and 'data-dt-img-description' attributes; 3) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts; 4) Sanitize and validate all user inputs at the application layer, potentially using custom plugins or filters to override the vulnerable theme’s behavior; 5) Regularly monitor website content for unexpected script injections; 6) Educate content contributors about the risks and enforce strong authentication mechanisms such as MFA; 7) Plan for prompt update or replacement of the The7 theme once a patch or secure version is available. Additionally, backup website data frequently to enable quick restoration if compromise occurs.
