CVE-2025-49076 is a stored Cross-site Scripting (XSS) vulnerability identified in POSIMYTH Innovations' The Plus Addons for Elementor Page Builder Lite plugin, affecting versions up to 6.2.7. This vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the plugin fails to adequately sanitize or encode user-supplied input before rendering it on web pages, allowing malicious scripts to be stored persistently and executed in the context of users visiting the affected site. The vulnerability requires low privileges (PR:L) and user interaction (UI:R) to exploit, but it can be triggered remotely (AV:N) without complex attack conditions (AC:L). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The CVSS v3.1 base score is 6.5, indicating a medium severity level. The impact includes potential confidentiality, integrity, and availability losses, such as session hijacking, defacement, or redirection to malicious sites. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects a widely used WordPress plugin that extends Elementor Page Builder functionality, which is popular among website developers for creating rich content layouts. Stored XSS vulnerabilities are particularly dangerous because they can affect all users who view the compromised content, including administrators, potentially leading to full site compromise or data theft.

For European organizations, especially those relying on WordPress websites enhanced with The Plus Addons for Elementor Page Builder Lite, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information, defacement of websites, or distribution of malware to visitors. Organizations in sectors such as e-commerce, government, education, and media that maintain public-facing websites using this plugin could suffer reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. Since the vulnerability allows scope change, attackers might leverage it as a foothold to escalate privileges or move laterally within the web infrastructure. The requirement for low privileges and user interaction means that attackers might target less privileged users or rely on social engineering to trigger the exploit. The lack of a patch increases the urgency for organizations to implement interim mitigations. Given the widespread use of Elementor and its addons in Europe, the potential impact is broad, affecting small businesses to large enterprises that depend on secure web presence.

1. Immediate mitigation should include disabling or removing The Plus Addons for Elementor Page Builder Lite plugin until an official patch is released. 2. Implement Web Application Firewall (WAF) rules to detect and block typical XSS payloads targeting the plugin's input fields. 3. Conduct thorough input validation and output encoding on all user-generated content, especially in custom implementations or extensions of the plugin. 4. Restrict user privileges to the minimum necessary, limiting access to plugin configuration and content editing to trusted administrators. 5. Monitor website logs for unusual input patterns or repeated attempts to inject scripts. 6. Educate users and administrators about the risks of clicking on suspicious links or executing untrusted scripts. 7. Once a patch is available, prioritize immediate testing and deployment. 8. Consider implementing Content Security Policy (CSP) headers to reduce the impact of potential XSS by restricting script execution sources. 9. Regularly back up website data and configurations to enable quick restoration in case of compromise.
