CVE-2025-30815: Hesabfa Accounting CSRF Vulnerability

CVE-2025-30815 Overview

CVE-2025-30815 is a Cross-Site Request Forgery (CSRF) vulnerability in the Hesabfa Accounting WordPress plugin developed by Saeed Sattar Beglou. The flaw affects all versions of the plugin up to and including 2.1.8. The issue is categorized under CWE-352, which covers missing or improperly validated anti-CSRF tokens on state-changing requests. An attacker can craft a malicious web page that, when visited by an authenticated WordPress user, submits unauthorized requests to the vulnerable plugin. Exploitation requires user interaction but no authentication on the attacker's side, making phishing-driven attacks the primary delivery method.

Critical Impact
Successful exploitation allows an attacker to trigger unauthorized state-changing actions in the Hesabfa Accounting plugin on behalf of an authenticated WordPress user.

Affected Products

Hesabfa Accounting WordPress plugin (hesabfa-accounting) versions up to and including 2.1.8
WordPress installations using the vulnerable plugin

Technical Details for CVE-2025-30815

Vulnerability Analysis

The Hesabfa Accounting plugin exposes state-changing endpoints that do not adequately validate anti-CSRF tokens (nonces in the WordPress ecosystem). An attacker hosts a malicious page containing a forged HTTP request targeting a plugin action. When an authenticated administrator or privileged user visits the page, the browser automatically attaches the WordPress session cookie, and the plugin processes the request as legitimate. The vulnerability requires user interaction, which aligns with typical CSRF exploitation via phishing links or malicious advertisements.

Root Cause

The root cause is missing or improperly verified CSRF protection on request handlers within the plugin. WordPress provides wp_nonce_field() and check_admin_referer() primitives for exactly this purpose. When plugin developers omit these checks, any authenticated user can be coerced into executing unintended administrative actions by an unauthenticated remote attacker.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker delivers a link or embeds a request in a page under their control. The victim must be authenticated to the WordPress admin session at the time of visiting the malicious content. Once triggered, the request is submitted with the victim's cookies, resulting in low integrity impact against the plugin's configuration or data. Confidentiality and availability are not directly affected by the base vulnerability.

No public proof-of-concept exploit code has been referenced in the advisory. See the Patchstack CSRF Vulnerability Advisory for additional technical context.

Detection Methods for CVE-2025-30815

Indicators of Compromise

Unexpected configuration changes or data modifications in the Hesabfa Accounting plugin without a corresponding administrator action in audit logs
HTTP POST requests to Hesabfa plugin endpoints originating from Referer headers pointing to external, untrusted domains
Access log entries showing plugin admin actions triggered immediately after a user clicks an external link

Detection Strategies

Inspect WordPress access logs for requests to wp-admin/admin.php?page=hesabfa* or admin-ajax.php calls invoking Hesabfa plugin actions with non-local Referer values
Monitor for missing or invalid _wpnonce parameters on POST requests targeting Hesabfa plugin handlers
Correlate authenticated session activity with browsing history to identify cross-site request patterns

Monitoring Recommendations

Enable WordPress audit logging plugins to capture administrative actions with source IP, user agent, and Referer values
Alert on any Hesabfa plugin configuration modifications outside of expected maintenance windows
Track outbound clicks from admin sessions and flag admins who navigate to external content while logged in

How to Mitigate CVE-2025-30815

Immediate Actions Required

Update the Hesabfa Accounting plugin to a version later than 2.1.8 once the vendor publishes a fix
Restrict WordPress administrative access to dedicated browsers or sessions not used for general web browsing
Enforce least-privilege on WordPress user roles so only necessary accounts can trigger plugin actions

Patch Information

At the time of publication, the advisory referenced by Patchstack indicates the vulnerability affects versions up to and including 2.1.8. Administrators should monitor the plugin's official channels for a patched release and apply updates as soon as they become available.

Workarounds

Deactivate the Hesabfa Accounting plugin until a fixed version is available if it is not business-critical
Deploy a Web Application Firewall (WAF) rule to block requests to plugin endpoints that lack a valid _wpnonce parameter or carry an external Referer
Require administrators to log out of the WordPress admin interface when not actively performing management tasks
Enforce SameSite=Strict or SameSite=Lax cookies at the reverse proxy or application layer to reduce cross-site cookie transmission

bash

# Example nginx snippet to block Hesabfa plugin POSTs with external Referer
location ~* /wp-admin/admin(-ajax)?\.php$ {
    if ($request_method = POST) {
        set $block 0;
        if ($args ~* "page=hesabfa") { set $block "${block}1"; }
        if ($http_referer !~* "^https?://your-domain\.tld/") { set $block "${block}1"; }
        if ($block = "011") { return 403; }
    }
}
