CVE-2025-49435 Overview
CVE-2025-49435 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the Hasina77 Wp Easy Allopass WordPress plugin. The flaw impacts all versions of wordpress-easy-allopass up to and including 4.1.1. An attacker can trick an authenticated user into submitting a forged request that performs state-changing actions within the plugin. Exploitation requires user interaction, such as clicking a crafted link or visiting an attacker-controlled page while authenticated. The vulnerability is network-accessible and requires no privileges on the attacker's side.
Critical Impact
An attacker can leverage an authenticated user's session to perform unauthorized actions in the Wp Easy Allopass plugin, resulting in limited integrity impact on affected WordPress installations.
Affected Products
- Hasina77 Wp Easy Allopass (wordpress-easy-allopass) — all versions through 4.1.1

Technical Details for CVE-2025-49435
Vulnerability Analysis
The vulnerability stems from the plugin's failure to validate the origin of state-changing HTTP requests. The Wp Easy Allopass plugin does not implement WordPress nonce verification (wp_verify_nonce) or equivalent anti-CSRF token checks on sensitive endpoints. This allows an attacker to craft malicious HTML or JavaScript that submits requests to the target WordPress site using the victim's authenticated session cookies.
The EPSS score is 0.136% (3.4 percentile), indicating low observed exploitation probability. However, CSRF flaws in WordPress plugins remain a common attack vector against site administrators.
Root Cause
The root cause is missing CSRF protection [CWE-352] on plugin request handlers. WordPress provides built-in nonce APIs (wp_nonce_field, check_admin_referer, wp_verify_nonce) to bind requests to a specific user session. The affected versions of wordpress-easy-allopass do not enforce these checks before processing user-supplied input on privileged actions.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker hosts a page containing an auto-submitting form or img/fetch request targeting the vulnerable plugin endpoint on the victim's WordPress site. When an authenticated user with access to the plugin visits the page, the browser attaches session cookies and executes the forged request. The impact is limited to integrity, with no direct confidentiality or availability loss based on the CVSS vector.
No verified proof-of-concept code is publicly available. See the Patchstack WordPress Vulnerability Advisory for advisory details.
Detection Methods for CVE-2025-49435
Indicators of Compromise
- Unexpected changes to Wp Easy Allopass plugin settings or configuration entries not initiated by administrators.
- HTTP POST requests to plugin endpoints with Referer headers pointing to external, untrusted domains.
- Administrator account activity originating from unusual client contexts shortly after visiting third-party sites.
Detection Strategies
- Review web server access logs for POST requests to wordpress-easy-allopass endpoints with missing or mismatched Referer and Origin headers.
- Enable WordPress audit logging plugins to record plugin option changes and correlate them with administrator browsing activity.
- Monitor for outbound HTTP requests from administrator workstations to unfamiliar domains preceding plugin configuration changes.
Monitoring Recommendations
- Track all administrative actions on WordPress sites through centralized logging with retention sufficient for incident review.
- Alert on plugin configuration modifications outside of scheduled maintenance windows.
- Baseline normal administrator browsing patterns and flag session activity that includes cross-origin form submissions to WordPress admin URLs.
How to Mitigate CVE-2025-49435
Immediate Actions Required
- Update the Wp Easy Allopass plugin to a version later than 4.1.1 once the vendor releases a patched release.
- If no patched version is available, deactivate and remove the wordpress-easy-allopass plugin until a fix ships.
- Require administrators to log out of WordPress sessions when not actively managing the site to reduce CSRF exposure.
Patch Information
At the time of publication, the Patchstack advisory confirms all versions up to and including 4.1.1 are affected. Administrators should monitor the plugin's official distribution channel for a fixed release addressing CWE-352.
Workarounds
- Deploy a Web Application Firewall (WAF) rule that blocks POST requests to plugin endpoints lacking a same-origin Referer header.
- Enforce browser isolation or separate browser profiles for WordPress administrative sessions.
- Restrict access to wp-admin by IP allowlist to limit CSRF exposure from unauthenticated networks.
