CVE-2025-68598 is a stored cross-site scripting (XSS) vulnerability found in the LiveComposer Page Builder plugin for WordPress, specifically affecting versions up to and including 2.0.5. The vulnerability stems from improper neutralization of 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 visit the affected pages, the malicious script executes in their browsers within the security context of the vulnerable site. This can lead to a range of attacks including session hijacking, credential theft, defacement, or unauthorized actions performed on behalf of the victim. The vulnerability does not require authentication to exploit, nor does it require user interaction beyond visiting a compromised page, increasing its risk profile. While no public exploits are currently reported, the nature of stored XSS vulnerabilities means that exploitation could be automated or weaponized in phishing campaigns. The affected product, LiveComposer Page Builder, is a popular WordPress plugin used for building and customizing websites, making the attack surface significant. The lack of a CVSS score indicates that the vulnerability is newly published and awaiting further assessment. The vulnerability was reserved and published in December 2025, with Patchstack as the assigner. No official patches or mitigation links are currently provided, emphasizing the need for vigilance and proactive defense measures.

For European organizations, the impact of this stored XSS vulnerability can be substantial. Many businesses and institutions in Europe rely on WordPress and its plugins like LiveComposer for their web presence. Exploitation could lead to unauthorized access to user accounts, leakage of sensitive information, and potential defacement or disruption of websites. This can damage organizational reputation, lead to regulatory non-compliance (especially under GDPR due to data breaches), and cause operational downtime. Attackers could leverage the vulnerability to implant persistent malicious scripts that harvest credentials or propagate malware to site visitors, including customers or employees. The impact is particularly critical for sectors with high web interaction such as e-commerce, government portals, and media outlets. Additionally, the ease of exploitation without authentication increases the likelihood of widespread attacks if the vulnerability becomes publicly exploited. The absence of known exploits currently provides a window for mitigation, but organizations must act swiftly to prevent compromise.

1. Monitor for official patches or updates from LiveComposer and apply them immediately once available to remediate the vulnerability. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block common XSS payloads targeting the LiveComposer plugin. 3. Conduct a thorough audit of all user-generated content inputs and sanitize or validate inputs rigorously to prevent injection of malicious scripts. 4. Restrict administrative access to the WordPress backend using multi-factor authentication and IP whitelisting to reduce risk from compromised accounts. 5. Regularly scan websites with vulnerability scanners that include checks for XSS vulnerabilities in plugins. 6. Educate website administrators and content editors about the risks of XSS and safe content management practices. 7. Consider temporarily disabling or replacing the LiveComposer plugin with alternative page builders until a secure version is released. 8. Monitor web server and application logs for unusual activity indicative of exploitation attempts. 9. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 10. Backup website data regularly to enable quick recovery in case of compromise.
