CVE-2025-54710: Tiktok Feed Authorization Bypass Flaw

CVE-2025-54710 Overview

CVE-2025-54710 is a Missing Authorization vulnerability [CWE-862] in the bPlugins Tiktok Feed plugin (b-tiktok-feed) for WordPress. The flaw affects all versions up to and including 1.0.21. Authenticated attackers with low-level privileges can access plugin functionality that is not properly constrained by Access Control Lists (ACLs). Successful exploitation can affect integrity and cause high availability impact on affected WordPress sites.

Critical Impact

Authenticated low-privilege users can invoke restricted plugin functions over the network, leading to integrity changes and denial of service on WordPress sites running vulnerable versions of Tiktok Feed.

Affected Products

• bPlugins Tiktok Feed (b-tiktok-feed) WordPress plugin
• All versions from n/a through 1.0.21
• WordPress sites with the plugin installed and activated

Technical Details for CVE-2025-54710

Vulnerability Analysis

The vulnerability stems from Broken Access Control in the Tiktok Feed plugin for WordPress. The plugin exposes functionality through endpoints that fail to enforce proper capability or role checks. An attacker with a low-privilege authenticated account, such as a Subscriber, can invoke actions that should be restricted to higher-privilege roles.

The attack is delivered over the network and requires no user interaction. Confidentiality is not impacted, but the issue allows limited integrity changes and produces a high availability impact, consistent with actions that can alter or disrupt plugin state on the host site.

This weakness is classified under CWE-862: Missing Authorization, which describes software that does not perform authorization checks when an actor attempts to access a resource or perform an action.

Root Cause

The root cause is the absence of capability verification on plugin handlers. WordPress plugins typically guard sensitive actions with current_user_can() checks and nonce validation via check_ajax_referer() or wp_verify_nonce(). In b-tiktok-feed versions up to 1.0.21, one or more handlers omit these checks, leaving them reachable by any authenticated user regardless of role.

Attack Vector

Exploitation requires network access to the WordPress site and a valid authenticated session with low privileges. The attacker submits requests to the unprotected plugin endpoints, such as AJAX actions registered via wp_ajax_* hooks, and triggers operations intended for administrators. Refer to the Patchstack Vulnerability Report for further technical context.

Detection Methods for CVE-2025-54710

Indicators of Compromise

• Unexpected modifications to Tiktok Feed plugin settings or stored options in the wp_options table.
• Authenticated POST requests from low-privilege accounts to admin-ajax.php invoking b-tiktok-feed related actions.
• Site availability disruptions or feed configuration changes that correlate with subscriber-level account activity.

Detection Strategies

• Audit WordPress access logs for admin-ajax.php and REST API calls referencing b-tiktok-feed actions issued by non-administrator users.
• Compare installed plugin versions against the fixed release using wp plugin list to identify hosts still running 1.0.21 or earlier.
• Review plugin source code for handlers missing current_user_can() capability checks and nonce verification.

Monitoring Recommendations

• Enable WordPress audit logging to record privilege-sensitive actions and changes initiated by low-privilege accounts.
• Alert on spikes in admin-ajax.php traffic originating from Subscriber-level sessions.
• Monitor for new or modified Subscriber accounts that subsequently issue plugin administrative actions.

How to Mitigate CVE-2025-54710

Immediate Actions Required

• Update the bPlugins Tiktok Feed plugin to a version newer than 1.0.21 once a patched release is available from the vendor.
• Disable or remove the b-tiktok-feed plugin on sites where an upgrade path is not immediately available.
• Review and reduce the number of low-privilege accounts on the WordPress instance, removing unused Subscriber accounts.

Patch Information

Consult the Patchstack Vulnerability Report for current patch availability. Administrators should upgrade to any release published after 1.0.21 that addresses the missing authorization checks. If no patched version is yet available, treat the plugin as vulnerable and apply compensating controls.

Workarounds

• Deactivate the plugin until a patched version is installed.
• Restrict access to admin-ajax.php and /wp-json/ endpoints to authenticated administrators using a Web Application Firewall (WAF) rule.
• Disable open user registration in Settings → General to prevent attackers from acquiring low-privilege accounts.

# Configuration example: identify and disable the vulnerable plugin via WP-CLI
wp plugin list --name=b-tiktok-feed --fields=name,status,version
wp plugin deactivate b-tiktok-feed
