CVE-2025-53444: 
WordPress vulnerability analysis and mitigation

CVE-2025-53444 is a Cross-Site Request Forgery (CSRF) vulnerability in the DeluxeThemes Userpro WordPress plugin affecting all versions before 5.1.11. It allows unauthenticated remote attackers to perform unauthorized actions on behalf of authenticated users by tricking them into interacting with a crafted request. The vulnerability was reported by Ananda Dhakal of Patchstack on May 13, 2024, and publicly disclosed on April 15, 2026. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack, GitHub Advisory).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), meaning the Userpro plugin fails to sufficiently verify whether state-changing requests were intentionally submitted by the authenticated user. An attacker can craft a malicious web page or link that, when visited by a logged-in user, silently submits a forged HTTP request to the WordPress site carrying the victim's session credentials. No privileges are required on the attacker's part, but user interaction (e.g., clicking a link or visiting a crafted page) is necessary for exploitation. The attack vector is network-based with low complexity (Patchstack, GitHub Advisory).

Successful exploitation allows an attacker to force a higher-privileged authenticated user to execute unintended actions within the Userpro plugin without their knowledge or consent, such as modifying user settings or account information. The impact is limited to integrity — there is no confidentiality or availability impact. The vulnerability does not enable direct data exfiltration or system compromise, but unauthorized modifications to user profiles or plugin configuration could facilitate further abuse (Patchstack).

There is no known public proof-of-concept exploit and no evidence of active in-the-wild exploitation at this time (GitHub Advisory). The EPSS score is approximately 0.014% (0.000140), placing it in the 4th percentile for exploitation likelihood within the next 30 days. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack rates the exploitation priority as Low, noting the issue is unlikely to be exploited (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Userpro plugin in a version prior to 5.1.11 using tools like WPScan or by inspecting publicly accessible plugin metadata.
2. Identify target action: Determine which Userpro plugin endpoints or form actions lack CSRF token validation (e.g., user profile update, settings change endpoints).
3. Craft malicious request: Create an HTML page or link containing a hidden form or auto-submitting JavaScript that sends a forged POST/GET request to the target WordPress site's vulnerable Userpro endpoint with attacker-chosen parameters.
4. Deliver to victim: Trick an authenticated Userpro user (ideally an administrator) into visiting the malicious page via phishing, social engineering, or embedding in a comment/forum post.
5. Action executed: The victim's browser automatically submits the forged request with their active session cookies, causing the Userpro plugin to process the unauthorized action (e.g., modifying account settings) on their behalf (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to Userpro plugin endpoints (e.g., wp-admin/admin-ajax.php or Userpro-specific action URLs) from unusual referrer origins or with no referrer header.
• Application: Unexplained changes to user profile fields, account settings, or Userpro plugin configuration that were not initiated by the account owner.
• Network: Requests to Userpro action endpoints originating from external or unfamiliar domains in the HTTP Referer header, which may indicate a cross-origin forged submission.

Update the Userpro plugin to version 5.1.11 or later, which contains the fix for this CSRF vulnerability (Patchstack). Patchstack users can enable auto-update for vulnerable plugins to receive protection automatically. As a general hardening measure, ensure that WordPress security plugins enforcing CSRF token validation are in place, and review access logs for any suspicious form submissions to Userpro endpoints.

The vulnerability was discovered and reported by Ananda Dhakal of Patchstack through their Active Vulnerability Disclosure Program (VDP), with an early warning sent to Patchstack customers on April 15, 2026, the same day it was publicly published (Patchstack). No significant broader media coverage or notable researcher commentary beyond the Patchstack disclosure has been identified.
