CVE-2025-49936 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the xtemos WoodMart WordPress theme, affecting all versions prior to 8.3.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, specifically within the client-side DOM environment. Unlike traditional reflected or stored XSS, DOM-based XSS occurs entirely on the client side, where malicious scripts are injected and executed through manipulation of the Document Object Model. Attackers can craft URLs or input vectors that, when processed by the vulnerable WoodMart theme, execute arbitrary JavaScript code in the victim’s browser. This can lead to theft of session cookies, redirection to malicious sites, or unauthorized actions performed with the victim’s privileges. The vulnerability does not require authentication, making it accessible to unauthenticated attackers. Although no public exploits have been reported yet, the disclosure and availability of details increase the risk of exploitation. The lack of a CVSS score indicates that the vulnerability is newly published and pending formal scoring, but the technical characteristics suggest a significant threat. WoodMart is widely used in e-commerce websites built on WordPress, making this vulnerability particularly relevant for online retailers. The vulnerability affects versions from initial releases up to but not including 8.3.2, so organizations running older versions remain vulnerable. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure. No official patches or mitigation links are provided in the source data, emphasizing the need for users to update promptly once patches are available or to apply interim mitigations.

For European organizations, especially those operating e-commerce platforms using the WoodMart theme, this DOM-based XSS vulnerability poses a significant risk. Successful exploitation can compromise the confidentiality of user data, including session tokens and personal information, leading to account takeover and fraud. Integrity can be affected as attackers may manipulate the content displayed to users or perform unauthorized actions on their behalf. Availability impact is generally limited in XSS but could occur if attackers inject scripts that disrupt site functionality or cause denial of service. The vulnerability does not require authentication, broadening the attack surface to all site visitors. Given the popularity of WordPress and WoodMart in European markets, especially in countries with mature e-commerce sectors like Germany, the UK, France, and the Netherlands, the potential for widespread impact is considerable. Additionally, regulatory frameworks such as GDPR impose strict requirements on protecting user data, so exploitation could lead to compliance violations and financial penalties. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for mitigation, as attackers often develop exploits rapidly after disclosure.

1. Update WoodMart theme to version 8.3.2 or later immediately once available, as this version addresses the vulnerability. 2. Until patching is possible, implement strict Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the risk of XSS exploitation. 3. Sanitize and validate all user inputs rigorously at both client and server sides to prevent injection of malicious scripts. 4. Employ security plugins or Web Application Firewalls (WAFs) that can detect and block XSS attack patterns targeting WordPress themes. 5. Conduct regular security audits and penetration testing focusing on client-side vulnerabilities, including DOM-based XSS. 6. Educate developers and administrators about secure coding practices related to DOM manipulation and input handling. 7. Monitor web traffic and logs for unusual activity or attempted exploitation attempts. 8. Consider implementing HTTP-only and Secure flags on cookies to mitigate session hijacking risks. These measures, combined with timely patching, will significantly reduce the risk posed by this vulnerability.
