CVE-2025-69021: 
WordPress vulnerability analysis and mitigation

CVE-2025-69021 is a Cross-Site Request Forgery (CSRF) vulnerability in the Ays Pro "Popup box" WordPress plugin (ays-popup-box). It affects all versions from n/a through 6.0.7 and was published on December 30, 2025, with Patchstack credited as the assigner. The vulnerability carries a CVSS v3.1 base score of 5.4 (Medium), though Feedly's category estimate rates it as High (Feedly, Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), meaning the plugin fails to properly validate or enforce anti-CSRF tokens on one or more state-changing requests. An attacker can craft a malicious web page or link that, when visited by an authenticated WordPress administrator or privileged user, silently submits forged requests to the plugin's endpoints. No authentication is required on the attacker's side; only user interaction (victim visiting the attacker-controlled page) is needed. The attack vector is network-based with low complexity (Feedly).

Successful exploitation results in limited but meaningful integrity and availability impacts — an attacker can manipulate plugin settings or data on behalf of an authenticated user without their knowledge or consent. Confidentiality is not directly impacted. The scope is limited to the affected WordPress installation, but unauthorized changes to popup configurations could be used to inject malicious content or disrupt site functionality (Feedly).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2025-69021. The EPSS score is extremely low at 0.000080 (~0.008%), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires social engineering to trick an authenticated WordPress user into visiting a malicious page (Feedly).

1. Reconnaissance: Identify WordPress sites running the Ays Pro Popup box plugin version 6.0.7 or earlier, using tools like WPScan or by inspecting plugin directories.
2. Identify target endpoint: Determine which plugin admin actions lack CSRF token validation (e.g., settings update or popup creation/deletion endpoints).
3. Craft malicious page: Create an HTML page containing a hidden form that auto-submits a forged POST request to the target WordPress site's admin endpoint (e.g., wp-admin/admin-post.php or wp-admin/admin-ajax.php) with the desired malicious parameters.
4. Deliver to victim: Trick an authenticated WordPress administrator into visiting the malicious page via phishing email, social media link, or embedded iframe.
5. Achieve objective: The victim's browser automatically submits the forged request with their session credentials, causing the plugin to execute the unauthorized action (e.g., modifying popup settings or injecting content) (Feedly).

• Logs: WordPress access logs showing unexpected POST requests to plugin admin endpoints (e.g., wp-admin/admin-post.php or wp-admin/admin-ajax.php) with Popup box action parameters from unusual referrer URLs or external domains.
• File System / Database: Unexpected or unauthorized changes to popup configurations in the WordPress database (wp_posts or plugin-specific tables) at unusual times or without corresponding admin activity.
• Logs: WordPress audit logs (if enabled via a plugin) recording plugin setting changes attributed to an administrator account at times inconsistent with that user's normal activity.

Users should update the Ays Pro Popup box plugin to a version beyond 6.0.7 that includes a fix for this CSRF vulnerability. Until a patched version is available or applied, administrators can mitigate risk by ensuring only trusted users have access to the WordPress admin panel and by using a Web Application Firewall (WAF) capable of detecting CSRF patterns. Disabling the plugin entirely is an option if it is not critical to site operations (Patchstack).
