CVE-2025-49269: Market Exporter CSRF Vulnerability

CVE-2025-49269 Overview

CVE-2025-49269 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Market Exporter plugin for WordPress, developed by Anton Vanyukov. The flaw impacts all versions of Market Exporter up to and including 2.0.22. An attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user, triggers unintended state-changing actions in the plugin. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery and requires user interaction to succeed.

Critical Impact
Successful exploitation allows an attacker to force an authenticated administrator to execute unwanted actions in the Market Exporter plugin, resulting in limited integrity impact on the WordPress site.

Affected Products

Anton Vanyukov Market Exporter WordPress plugin
All versions from n/a through 2.0.22
WordPress installations with the vulnerable plugin activated

Technical Details for CVE-2025-49269

Vulnerability Analysis

The Market Exporter plugin fails to properly validate the origin of state-changing HTTP requests. WordPress provides a nonce mechanism (wp_nonce_field, check_admin_referer, wp_verify_nonce) to protect administrative actions against CSRF, but the affected plugin endpoints do not enforce this validation on all sensitive operations up through version 2.0.22.

Exploitation requires an authenticated user, typically an administrator, to interact with attacker-controlled content while logged into WordPress. The attack vector is network-based with low complexity, but user interaction is required, and only integrity is affected. Confidentiality and availability remain unaffected. The EPSS score indicates a low probability of exploitation in the near term.

Root Cause

The root cause is missing or insufficient anti-CSRF token verification on plugin request handlers. Without a valid nonce check tied to the user session, the WordPress backend cannot distinguish between a legitimate administrator submission and a forged request originating from a third-party site.

Attack Vector

An attacker hosts a page containing a hidden form or JavaScript payload that submits a request to a vulnerable Market Exporter endpoint on the target WordPress site. When an authenticated administrator visits the page, the browser automatically attaches session cookies, causing the plugin to process the forged action as legitimate. Refer to the Patchstack advisory for additional technical detail.

Detection Methods for CVE-2025-49269

Indicators of Compromise

Unexpected changes to Market Exporter plugin settings or generated export files without corresponding administrator actions in the audit log
HTTP referer headers pointing to unfamiliar external domains on requests targeting wp-admin/admin.php?page=market-exporter or related plugin endpoints
POST requests to plugin endpoints lacking a valid _wpnonce parameter

Detection Strategies

Inspect WordPress access logs for state-changing POST or GET requests to Market Exporter routes originating from cross-origin referers
Enable and review WordPress audit logging plugins to correlate administrator sessions with plugin configuration changes
Monitor for anomalous administrator activity occurring shortly after external link clicks or email interactions

Monitoring Recommendations

Deploy a Web Application Firewall (WAF) with rules that flag requests to plugin admin endpoints missing nonce parameters
Alert on modifications to Market Exporter configuration files or export outputs outside scheduled operations
Track administrator browser sessions for concurrent visits to external sites and WordPress admin actions

How to Mitigate CVE-2025-49269

Immediate Actions Required

Update the Market Exporter plugin to a version later than 2.0.22 as soon as the vendor publishes a fixed release
Restrict WordPress administrator accounts from browsing untrusted content in the same session used for site administration
Audit recent Market Exporter activity and revert any unauthorized configuration or export changes

Patch Information

At the time of publication, the NVD entry references the Patchstack advisory for CVE-2025-49269. Administrators should monitor the plugin's official WordPress.org listing for a patched release above version 2.0.22 and apply it promptly.

Workarounds

Deactivate and remove the Market Exporter plugin until a fixed version is available if the export functionality is not business-critical
Enforce strict same-site cookie attributes on WordPress session cookies to reduce cross-origin request risk
Require administrators to use dedicated browsers or profiles for WordPress administration, isolating admin sessions from general browsing

bash

# Configuration example: temporarily disable the plugin via WP-CLI
wp plugin deactivate market-exporter
wp plugin status market-exporter
