Overview
A Stored Cross-Site Scripting (XSS) vulnerability, identified as CVE-2025-66053, has been discovered in the Kriesi Enfold WordPress theme. This vulnerability affects versions 7.1.2 and earlier. Stored XSS vulnerabilities allow attackers to inject malicious scripts that are permanently stored on the server (e.g., in the database). When other users access the affected pages, these scripts are executed in their browsers, potentially leading to data theft, session hijacking, or website defacement.
Technical Details
The vulnerability stems from the improper neutralization of user-supplied input during web page generation. Specifically, the Enfold theme fails to adequately sanitize certain input fields, allowing attackers to inject malicious JavaScript code. This injected code is then stored in the database and executed when a user views the page containing the malicious input. The specific input vector affected is not specified in the provided vulnerability report but the report suggests the possibility of multiple injection points throughout the Enfold theme’s features.
CVSS Analysis
According to the provided information, both the Severity and CVSS Score for CVE-2025-66053 are currently listed as “N/A.” This likely indicates that the CVSS score has not yet been formally calculated, or that the reporting organization deemed the vulnerability’s impact to be context-dependent and therefore difficult to quantify with a standard CVSS score. It is crucial to monitor official advisories for updated severity assessments.
Possible Impact
The impact of a Stored XSS vulnerability can be significant. A successful exploit can allow an attacker to:
- Steal user session cookies, granting unauthorized access to user accounts.
- Deface the website, damaging its reputation and potentially disrupting business operations.
- Redirect users to malicious websites, potentially leading to phishing attacks or malware infections.
- Inject malicious JavaScript code that can perform actions on behalf of the user, such as changing passwords or making unauthorized purchases.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-66053, it is imperative that all Enfold theme users take the following steps:
- Update to the latest version: Immediately update your Enfold theme to the latest available version. The vulnerability is patched in versions later than 7.1.2. Access your WordPress dashboard and navigate to Appearance > Themes to check for updates.
- Monitor for updates: Keep your WordPress installation and all plugins and themes updated regularly.
- Consider a Web Application Firewall (WAF): Implement a WAF to provide an additional layer of security against XSS and other web-based attacks.
- Scan for malicious content: After updating, consider running a security scan to check for any potentially malicious content that may have been injected prior to patching.
