CVE-2025-14163 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Premium Addons for Elementor plugin for WordPress, affecting all versions up to and including 4.11.53. The vulnerability stems from the absence of nonce validation in the 'insert_inner_template' function, which is responsible for handling the insertion of Elementor templates. Nonce validation is a security mechanism designed to ensure that requests are legitimate and originate from authorized users. Without this protection, an attacker can craft a malicious request that, when executed by a user with the 'edit_posts' capability (typically site administrators or editors), results in the creation of arbitrary Elementor templates. This can be achieved by tricking the user into clicking a specially crafted link or visiting a malicious webpage, thereby exploiting the CSRF flaw. The attacker does not need to be authenticated, but the victim must have sufficient privileges and perform an action that triggers the request. The CVSS v3.1 base score is 4.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality impact (C:N), limited integrity impact (I:L), and no availability impact (A:N). Although no known exploits are currently reported in the wild, the vulnerability poses a risk of unauthorized template injection, which could be leveraged for website defacement, phishing, or as a foothold for further attacks. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for interim mitigations.

For European organizations utilizing WordPress with the Premium Addons for Elementor plugin, this vulnerability could lead to unauthorized creation of Elementor templates, potentially allowing attackers to manipulate website content or embed malicious code indirectly. While the direct confidentiality impact is minimal, the integrity of website content can be compromised, undermining trust and brand reputation. This could facilitate phishing campaigns, defacement, or indirect delivery of malware to site visitors. The attack requires user interaction and privileges, so the risk is concentrated on users with editing capabilities, often administrators or content managers. Organizations with large editorial teams or less stringent user privilege management are at higher risk. The medium severity score reflects that while the attack is not trivial, the potential for damage exists, especially in sectors where website integrity is critical, such as e-commerce, government portals, and media outlets. Disruption of website content can also lead to financial losses and regulatory scrutiny under GDPR if user trust is eroded or personal data is indirectly exposed.

1. Monitor for plugin updates from leap13 and apply patches immediately once available to address the nonce validation issue. 2. Until a patch is released, restrict the number of users with 'edit_posts' capability to the minimum necessary and enforce strong authentication measures for these accounts. 3. Implement additional CSRF protections at the web application firewall (WAF) level to detect and block suspicious cross-site requests targeting the vulnerable function. 4. Educate users with editing privileges about the risks of clicking on untrusted links or visiting unknown websites to reduce the likelihood of social engineering exploitation. 5. Conduct regular audits of Elementor templates to detect unauthorized or suspicious additions promptly. 6. Consider deploying Content Security Policy (CSP) headers to limit the impact of injected content. 7. Use security plugins that can add nonce validation or CSRF protection layers if available. 8. Review and harden WordPress security configurations, including limiting plugin installations and enforcing least privilege principles.
