CVE-2025-26745 identifies a stored cross-site scripting (XSS) vulnerability in the RS Elements Elementor Addon (rselements-lite) for WordPress, specifically affecting versions up to and including 1.1.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious JavaScript code that is stored on the server and executed in the browsers of users who visit the affected pages. Stored XSS is particularly dangerous because the malicious payload persists on the website and can affect multiple users without requiring repeated attacker interaction. This vulnerability does not require authentication, meaning any unauthenticated attacker can exploit it by submitting crafted input to the vulnerable component. The RS Elements Elementor Addon is a plugin used to extend the Elementor page builder functionality in WordPress, which is a widely used content management system globally. Although no public exploits have been reported yet, the vulnerability's nature makes it a prime candidate for exploitation once weaponized. The lack of a CVSS score indicates that the vulnerability is newly published, but based on the characteristics, it poses a significant risk to affected sites. Attackers exploiting this vulnerability could steal session cookies, deface websites, redirect users to malicious sites, or conduct other malicious activities that compromise user confidentiality and website integrity. The vulnerability affects all versions up to 1.1.5, and no official patches or updates are currently linked, so mitigation may require manual intervention or disabling the vulnerable addon until a fix is available.

The impact of CVE-2025-26745 on organizations worldwide can be substantial, especially for those relying on the RS Elements Elementor Addon in their WordPress environments. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the affected website, potentially leading to theft of sensitive user data such as authentication cookies, personal information, or payment details. This can result in account takeover, unauthorized access, and further compromise of internal systems. Additionally, attackers could deface websites or redirect visitors to phishing or malware distribution sites, damaging organizational reputation and trust. The persistent nature of stored XSS increases the risk as multiple users can be affected over time without repeated attacker effort. For e-commerce, financial, healthcare, and governmental websites using this addon, the consequences could include regulatory penalties, financial losses, and erosion of customer confidence. Moreover, the vulnerability could be leveraged as a foothold for more advanced attacks, including lateral movement within networks or delivering ransomware payloads. Given the widespread use of WordPress and Elementor, the scope of affected systems is broad, increasing the potential global impact.

To mitigate CVE-2025-26745, organizations should first verify if they are using the RS Elements Elementor Addon version 1.1.5 or earlier. Immediate steps include disabling or uninstalling the vulnerable addon until a security patch is released by the vendor. If disabling is not feasible, implement strict input validation and output encoding on all user-supplied data processed by the addon to neutralize malicious scripts. Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting this plugin. Regularly monitor website content for unauthorized script injections and anomalous behavior. Additionally, ensure that all WordPress core, themes, and plugins are kept up to date to reduce the attack surface. Educate site administrators about the risks of installing unverified plugins and encourage the use of security plugins that can detect and prevent XSS attacks. Finally, maintain regular backups of website data to enable quick restoration in case of compromise. Coordination with the vendor to obtain patches or updates as soon as they become available is critical for long-term remediation.
