CVE-2025-63033 is a stored cross-site scripting (XSS) vulnerability identified in the 'Make Section & Column Clickable For Elementor' WordPress plugin by Riyadh Ahmed, affecting all versions up to and including 2.3. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker with high privileges (such as an administrator) to inject malicious scripts that are stored persistently and executed when other users view the affected pages. The CVSS 3.1 base score is 5.9, indicating a medium severity level. The vector string (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) shows that the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction, and it affects confidentiality, integrity, and availability to a limited extent. The vulnerability's scope is changed (S:C), meaning it can affect resources beyond the initially vulnerable component. No public exploits have been reported yet, but the stored XSS nature means that if exploited, attackers could execute arbitrary JavaScript in the context of other users, potentially leading to session hijacking, defacement, or malware delivery. The plugin is used in conjunction with Elementor, a popular WordPress page builder, which increases the potential attack surface on websites using this combination. The vulnerability was published on December 9, 2025, and no patch links are currently available, indicating that remediation may still be pending or in progress.

For European organizations, this vulnerability poses a moderate risk primarily to websites using WordPress with the vulnerable plugin and Elementor. Successful exploitation could lead to unauthorized script execution in the browsers of site visitors or administrators, potentially resulting in session hijacking, theft of sensitive information, unauthorized actions on behalf of users, or distribution of malware. This can damage organizational reputation, lead to data breaches, and disrupt business operations. Given the reliance on WordPress for many corporate and e-commerce websites in Europe, the impact could be significant for sectors such as finance, retail, and public services. The requirement for high privileges to exploit reduces the risk from external attackers but raises concerns about insider threats or compromised administrator accounts. The stored nature of the XSS means that once injected, the malicious payload can affect multiple users over time, increasing the potential damage.

1. Monitor for and restrict administrative access to the WordPress backend and specifically to the 'Make Section & Column Clickable For Elementor' plugin settings to trusted personnel only. 2. Implement strict input validation and sanitization on all user inputs related to this plugin, if custom modifications are possible. 3. Deploy a Web Application Firewall (WAF) with rules tuned to detect and block XSS payloads targeting WordPress and Elementor plugins. 4. Regularly audit WordPress plugins and themes for updates and apply patches immediately once available for this vulnerability. 5. Conduct periodic security reviews and penetration tests focusing on WordPress installations using Elementor and related plugins. 6. Educate administrators about the risks of stored XSS and the importance of cautious input handling and privilege management. 7. Consider isolating or disabling the vulnerable plugin if immediate patching is not feasible, especially on high-value or public-facing sites. 8. Monitor logs for unusual activity or unexpected script injections related to the plugin’s functionality.
