What is CVE-2026-22461?

CVE-2026-22461 is a medium-severity vulnerability in the CTX Feed plugin for WordPress, specifically versions up to and including 6.6.18. It is caused by a missing authorization check, allowing unauthenticated attackers to perform administrative actions.

How does the vulnerability work?

The vulnerability arises from insufficient capability checks in the plugin’s functions, allowing attackers to access sensitive endpoints without authentication. By sending HTTP requests to specific WordPress endpoints, attackers can execute unauthorized actions.

Who is affected by this vulnerability?

Any WordPress site using the CTX Feed plugin version 6.6.18 or earlier is potentially affected. Site administrators should verify their plugin version to assess their risk.

How can I check if my site is vulnerable?

To check if your site is vulnerable, verify the version of the CTX Feed plugin installed. If it is version 6.6.18 or earlier, your site is at risk. Additionally, review the plugin’s settings and logs for any unauthorized access.

How can I fix this vulnerability?

To mitigate this vulnerability, update the CTX Feed plugin to version 6.6.19 or later, which includes the necessary authorization checks. Regularly check for updates to ensure ongoing security.

What does the CVSS score of 5.3 indicate?

The CVSS score of 5.3 indicates a medium severity level, suggesting that while the vulnerability is not critical, it can still lead to significant unauthorized access and potential data exposure if exploited.

What practical risks does this vulnerability pose?

If exploited, the vulnerability allows unauthorized users to perform administrative actions, such as downloading sensitive logs or modifying product data. This can lead to data breaches and disruption of e-commerce operations.

What are the key endpoints affected by this vulnerability?

Key vulnerable endpoints include AJAX handlers for Facebook, Google, Pinterest, and TikTok tracking, as well as administrative functions like downloading logs and importing/exporting feed configurations.

How does the proof of concept demonstrate the issue?

The proof of concept illustrates how an attacker can send requests to the vulnerable endpoints without authentication, showcasing the ease of exploitation. It highlights the lack of nonce validation and capability checks.

What should I do if I cannot update the plugin immediately?

If you cannot update the plugin immediately, consider disabling the plugin to prevent unauthorized access. Additionally, monitor your site for unusual activity and restrict access to sensitive endpoints if possible.

Are there any known exploits in the wild?

As of now, there are no public reports of active exploits targeting CVE-2026-22461. However, given its nature, it is advisable to apply the patch promptly to avoid potential exploitation.

Analysis Overview

Atomic Edge analysis of CVE-2026-22461:
The CTX Feed WordPress plugin, versions up to and including 6.6.18, contains a missing authorization vulnerability. This flaw allows unauthenticated attackers to perform administrative actions due to insufficient capability checks across multiple plugin components. The CVSS score of 5.3 reflects a medium-severity authorization bypass affecting core plugin functionality.

Atomic Edge research identified the root cause as the complete absence of capability checks in the `get_item_permissions_check` function within `/V5/API/RestController.php`. The original function (lines 86-111) performed role-based validation but failed to verify user authentication. Additionally, multiple AJAX handlers and administrative functions lacked proper `current_user_can(‘manage_woocommerce’)` checks. Key vulnerable endpoints included the `ajax_add_to_cart_data` functions in FacebookTracker, GoogleTracker, PinterestTracker, and TiktokTracker classes, which registered `wp_ajax_nopriv_` hooks allowing unauthenticated access. Administrative functions in DownloadFiles, ExportFeed, ImportFeed, and various helper functions also omitted capability verification.

Exploitation requires sending HTTP requests to specific WordPress endpoints without authentication. For AJAX endpoints, attackers send POST requests to `/wp-admin/admin-ajax.php` with `action=add_to_cart_facebook_pixel` (or similar tracker actions). For REST API endpoints, attackers access `/wp-json/ctxfeed/v1/` routes. Direct administrative actions target endpoints like `/wp-admin/admin-post.php?action=wpf_download_log` or similar plugin-specific handlers. The attack vector requires no special payloads, only knowledge of the vulnerable endpoint names and parameters documented in the plugin code.

The patch implements comprehensive authorization checks across 18 files. The primary fix replaces the flawed `get_item_permissions_check` function with a proper implementation that first checks `is_user_logged_in()` and then verifies `current_user_can(‘manage_woocommerce’)` or `current_user_can(‘manage_options’)`. All AJAX handlers remove `wp_ajax_nopriv_` hooks and add `current_user_can(‘manage_woocommerce’)` checks with proper nonce verification. Administrative functions in DownloadFiles, ExportFeed, ImportFeed, and helper.php receive similar capability checks. The plugin version updates from 6.6.18 to 6.6.19 in both the main plugin file and constants class.

Successful exploitation allows unauthenticated attackers to perform administrative actions including downloading feed logs, exporting/importing feed configurations, manipulating product tracking data for Facebook, Google, Pinterest, and TikTok integrations, clearing plugin cache data, modifying product attributes, and dismissing administrative notices. While the vulnerability does not provide direct remote code execution, it enables unauthorized access to sensitive e-commerce data and disruption of feed generation processes critical for product marketing channels.
