CVE-2025-48131 is a medium-severity vulnerability classified as CWE-79, indicating an Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the Saiful Islam UltraAddons Elementor Lite plugin, specifically versions up to 2.0.0. The flaw allows attackers to inject malicious scripts that are stored persistently within the application, which are then executed in the context of users' browsers when they access affected pages. The vulnerability is exploitable remotely (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact includes low confidentiality, integrity, and availability impacts (C:L/I:L/A:L), but the persistent nature of the XSS can lead to session hijacking, defacement, or distribution of malware. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability was reserved and published in May 2025, with enrichment from CISA and Patchstack. UltraAddons Elementor Lite is a WordPress plugin used to extend Elementor page builder functionality, popular among website developers for creating rich content. Stored XSS in such a plugin can be leveraged to compromise site visitors and administrators, potentially leading to broader site compromise or data leakage.

For European organizations, this vulnerability poses a significant risk especially to those relying on WordPress websites enhanced with UltraAddons Elementor Lite. The stored XSS can lead to unauthorized script execution in the browsers of site administrators or visitors, enabling theft of authentication tokens, defacement, or redirection to malicious sites. This can damage brand reputation, lead to data breaches involving personal data protected under GDPR, and cause operational disruptions. Organizations in sectors such as e-commerce, government, education, and media, which often use WordPress for public-facing sites, are particularly vulnerable. The requirement for some privileges and user interaction means attackers may target lower-privileged users or trick users into clicking crafted links, increasing the attack surface. The cross-site scripting can also be chained with other vulnerabilities to escalate privileges or implant persistent backdoors. Given the medium CVSS score and the widespread use of WordPress in Europe, the impact can be material if exploited.

European organizations should immediately audit their WordPress installations to identify the presence of UltraAddons Elementor Lite plugin, especially versions up to 2.0.0. Until an official patch is released, organizations should consider disabling or removing the plugin if feasible. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting this plugin can reduce risk. Administrators should enforce strict Content Security Policies (CSP) to limit script execution sources, mitigating the impact of injected scripts. Regularly scanning websites for XSS vulnerabilities using automated tools and manual testing is recommended. User privileges should be minimized to reduce the risk of exploitation requiring authentication. Additionally, educating users about phishing and social engineering tactics can reduce successful user interaction exploitation. Monitoring website logs for suspicious activity and unusual input patterns can help detect attempted exploitation. Once a patch is available, prompt application of updates is critical. Backup strategies should be reviewed to ensure rapid recovery in case of compromise.
