CVE-2025-1455 is a stored cross-site scripting (XSS) vulnerability identified in the Royal Elementor Addons and Templates plugin for WordPress, specifically affecting the Woo Grid widget component. This vulnerability arises from improper neutralization of input during web page generation (CWE-79), where the plugin fails to adequately sanitize and escape user-supplied input before rendering it on web pages. As a result, authenticated attackers with Contributor-level privileges or higher can inject arbitrary JavaScript code into pages. These malicious scripts are persistently stored and executed in the context of any user who accesses the compromised page, potentially leading to session hijacking, unauthorized actions, or defacement. The vulnerability affects all versions up to and including 1.7.1012. The CVSS v3.1 base score is 6.4, reflecting medium severity, with an attack vector of network (remote), low attack complexity, requiring privileges (Contributor or above), no user interaction, and scope change due to impact on other users. No patches or official fixes have been released yet, and no known exploits are reported in the wild. The vulnerability was reserved in February 2025 and published in April 2025. The flaw is significant because Contributor-level users are commonly allowed on WordPress sites to add content, making this a realistic threat vector. The persistent nature of stored XSS increases the risk compared to reflected XSS, as the malicious payload remains on the site until removed.

The impact of CVE-2025-1455 on organizations worldwide can be substantial, particularly for those relying on WordPress sites with the Royal Elementor Addons and Templates plugin installed. Successful exploitation allows attackers to execute arbitrary scripts in the browsers of site visitors, potentially leading to session hijacking, theft of authentication cookies, unauthorized actions performed on behalf of users, defacement of website content, or redirection to malicious sites. This can damage organizational reputation, lead to data breaches, and compromise user trust. Since the vulnerability requires Contributor-level access, attackers may leverage compromised or malicious contributor accounts to escalate their impact. The scope change in the CVSS vector indicates that the attack affects resources beyond the attacker’s privileges, increasing risk. Although no known exploits are currently reported, the medium severity and ease of exploitation with low complexity suggest that attackers may develop exploits soon. Organizations with public-facing WordPress sites, especially those allowing multiple contributors, are at higher risk. The lack of a patch increases exposure time, emphasizing the need for proactive mitigation.

To mitigate CVE-2025-1455 effectively, organizations should implement a multi-layered approach beyond generic advice: 1) Immediately review and restrict Contributor-level access to trusted users only, minimizing the attack surface. 2) Employ a Web Application Firewall (WAF) with custom rules to detect and block suspicious script injection attempts targeting the Woo Grid widget parameters. 3) Monitor WordPress site content regularly for unexpected or suspicious script tags or injected code, using automated scanning tools specialized in XSS detection. 4) Disable or remove the Royal Elementor Addons and Templates plugin if it is not essential, or replace it with alternative plugins that have no known vulnerabilities. 5) Keep WordPress core and all plugins updated; monitor vendor announcements for patches addressing this vulnerability and apply them promptly once available. 6) Implement Content Security Policy (CSP) headers to restrict execution of unauthorized scripts on the site. 7) Educate site administrators and contributors about the risks of XSS and safe content practices. 8) Consider deploying multi-factor authentication (MFA) for all user accounts to reduce the risk of account compromise that could lead to exploitation.
