CVE-2024-7611 is a stored cross-site scripting (XSS) vulnerability identified in the Enter Addons – Ultimate Template Builder for Elementor WordPress plugin, affecting all versions up to and including 2.1.8. The vulnerability stems from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'tag' attribute in the Events Card widget. Authenticated attackers with contributor-level permissions or higher can exploit this flaw by injecting arbitrary JavaScript code into the 'tag' attribute. Because the malicious script is stored persistently in the page content, it executes automatically whenever any user accesses the compromised page, potentially leading to session hijacking, privilege escalation, or other malicious actions. The vulnerability does not require user interaction beyond page viewing and has a CVSS 3.1 base score of 6.4, indicating medium severity. The attack vector is network-based, with low attack complexity, but requires privileges (authenticated contributor or above). The scope is changed since the vulnerability affects other users viewing the injected content. No patches or official fixes are currently linked, and no known exploits are reported in the wild. This vulnerability highlights the risks of insufficient input validation in WordPress plugins, especially those that allow user-generated content to be rendered on public-facing pages.

The impact of CVE-2024-7611 is significant for organizations using the Enter Addons – Ultimate Template Builder for Elementor plugin, especially those allowing contributor-level user access. Successful exploitation can lead to persistent XSS attacks, enabling attackers to steal session cookies, perform actions on behalf of other users, deface websites, or deliver malware. This can compromise the confidentiality and integrity of user data and potentially lead to broader network compromise if administrative accounts are targeted. Since the vulnerability requires authenticated access, the risk is somewhat mitigated by access controls; however, many WordPress sites allow contributor or author roles for content creation, increasing exposure. The vulnerability can affect website visitors and administrators alike, potentially damaging organizational reputation and trust. Additionally, exploitation could facilitate further attacks such as phishing or lateral movement within the network. The lack of a patch increases the urgency for mitigation. Overall, the threat poses a medium-level risk but with potential for serious consequences if leveraged in targeted attacks.

To mitigate CVE-2024-7611, organizations should immediately review user roles and restrict contributor-level access to trusted users only, minimizing the risk of malicious input. Implement a web application firewall (WAF) with rules to detect and block common XSS payloads targeting the 'tag' attribute or Events Card widget. Employ content security policies (CSP) to limit script execution from untrusted sources. Monitor and audit changes to pages using the vulnerable widget to detect suspicious modifications. Until an official patch is released, consider disabling or removing the Enter Addons – Ultimate Template Builder plugin if feasible. For sites requiring the plugin, sanitize and validate all user inputs rigorously at the application level, possibly via custom filters or hooks in WordPress. Educate content creators about the risks of injecting untrusted content. Regularly back up website data to enable recovery from compromise. Stay alert for vendor updates or patches and apply them promptly once available.
