CVE-2025-26899: Recapture for WooCommerce CSRF Vulnerability

CVE-2025-26899 Overview

CVE-2025-26899 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the Recapture Cart Recovery and Email Marketing plugin (recapture-for-woocommerce) for WordPress. The flaw impacts all plugin versions up to and including 1.0.43. An attacker can craft a malicious web page that, when visited by an authenticated administrator, triggers unauthorized changes to plugin settings on the target WooCommerce site. Exploitation requires user interaction from a privileged user but no valid credentials for the attacker. The vulnerability is tracked with a CVSS 3.1 score of 6.5 and an EPSS probability of 0.168%.

Critical Impact
Successful exploitation allows an attacker to modify Recapture plugin settings on WooCommerce stores by tricking a logged-in administrator into visiting an attacker-controlled URL.

Technical Details for CVE-2025-26899

Vulnerability Analysis

The Recapture for WooCommerce plugin exposes settings-modification endpoints that do not adequately verify the origin or intent of incoming state-changing requests. WordPress plugins typically defend against CSRF by validating nonces via check_admin_referer() or wp_verify_nonce() before processing POST or GET actions that alter configuration. In vulnerable releases up to 1.0.43, this verification is either missing or improperly implemented on the affected settings handlers.

An attacker who can lure an authenticated WordPress administrator to a malicious page can cause the browser to submit a forged request to wp-admin endpoints exposed by the plugin. The administrator's session cookies are automatically attached, and the request is processed as legitimate.

Root Cause

The root cause is missing or insufficient CSRF protection [CWE-352] on state-changing request handlers within the plugin. The affected handlers do not require, or do not correctly validate, a WordPress nonce token that binds the request to the current administrative session.

Attack Vector

Exploitation occurs over the network and requires an administrator to interact with attacker-controlled content, such as a link or auto-submitting HTML form hosted on an external site. Once the administrator visits the malicious page, the browser issues a cross-origin request to the WooCommerce site, which processes the settings change under the administrator's authenticated context. The attacker does not need to authenticate directly to the target site. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-26899

Indicators of Compromise

Unexpected modifications to Recapture plugin configuration values, including API keys, webhook targets, or email templates.
HTTP POST requests to wp-admin/admin.php or wp-admin/options.php with a Referer header pointing to an external domain.
WordPress audit log entries showing settings changes performed by an administrator immediately after visiting an external site.

Detection Strategies

Inspect web server access logs for state-changing requests to plugin endpoints containing recapture in the URI path, correlated with off-site referrers.
Enable a WordPress activity logging plugin and alert on modifications to Recapture settings outside expected maintenance windows.
Compare current plugin settings against a known-good baseline to identify unauthorized drift.

Monitoring Recommendations

Monitor administrator sessions for anomalous cross-site navigation followed by administrative actions within short time windows.
Alert on requests to admin-ajax.php or plugin-specific endpoints that lack the expected _wpnonce parameter.
Track outbound traffic from the WooCommerce site to unfamiliar hosts that may indicate attacker-controlled callback destinations set through modified plugin settings.

How to Mitigate CVE-2025-26899

Immediate Actions Required

Update the Recapture for WooCommerce plugin to a version later than 1.0.43 as soon as a patched release is available from the vendor.
Audit current Recapture plugin settings and revert any unauthorized changes.
Force administrator re-authentication and rotate any API keys or credentials stored in the plugin configuration.

Patch Information

At the time of publication, the vulnerability affects all versions through 1.0.43. Administrators should consult the Patchstack advisory and the plugin's WordPress.org page for the current fixed version and upgrade instructions.

Workarounds

Temporarily deactivate the Recapture for WooCommerce plugin until a patched version is installed.
Restrict wp-admin access by IP allowlist at the web server or WAF layer to limit exposure of authenticated sessions.
Deploy a web application firewall rule that blocks state-changing requests to plugin endpoints when the Referer header does not match the site's own origin.
Enforce administrator use of isolated browser profiles or sessions that do not share cookies with general browsing activity.

bash

# Example nginx rule to block cross-origin POSTs to wp-admin
map $http_referer $csrf_block {
    default 1;
    "~^https?://your-woocommerce-site\.example/" 0;
}

server {
    location ~ ^/wp-admin/ {
        if ($request_method = POST) {
            set $test "${csrf_block}";
            if ($test = 1) { return 403; }
        }
    }
}
