CVE-2026-6446: My Social Feeds <= 1.0.4 – Missing Authorization to Unauthenticated Sensitive Information Exposure via 'ttp_get_accounts' AJAX Action (my-social-feeds)

CVE ID CVE-2026-6446
Plugin my-social-feeds
Severity Medium (CVSS 5.4)
CWE 522
Vulnerable Version 1.0.4
Patched Version 1.0.5
Disclosed April 30, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-6446:

This vulnerability allows authenticated attackers with Subscriber-level access to retrieve sensitive TikTok OAuth credentials from the My Social Feeds plugin. The plugin fails to enforce authorization checks on the ‘ttp_get_accounts’ AJAX action. The get_accounts() function in the TiktokAPI.php file returns the full contents of the ‘ttp_tiktok_accounts’ WordPress option, which includes access_token and refresh_token values.

Root Cause: The get_accounts() function in my-social-feeds/includes/TiktokAPI.php (line 184) lacked proper authorization checks. The original code checked for ‘manage_options’ capability but did not verify a nonce. The AJAX action ‘ttp_get_accounts’ was registered without capability requirements. The function returned the raw ‘ttp_tiktok_accounts’ option without sanitizing sensitive fields.

Exploitation: An authenticated attacker with Subscriber-level access sends a GET request to /wp-admin/admin-ajax.php with action=ttp_get_accounts. The server responds with the full array of TikTok account data, including access_token and refresh_token. These tokens allow the attacker to impersonate the site owner when making API calls to TikTok’s servers.

Patch Analysis: The patch adds two security controls. First, it verifies a nonce using wp_verify_nonce() with ‘ttp_public_video_nonce’. Second, it filters the returned account data to exclude access_token and refresh_token fields. The sanitized response only includes account_id, display_name, avatar_url, follower_count, and created_at. The nonce is now passed via GET parameter and validated before processing.

Impact: Successful exploitation exposes TikTok OAuth tokens that provide API access. An attacker can use these tokens to perform actions on behalf of the site owner within the TikTok API, including posting content, reading direct messages, or accessing analytics data. This represents a significant breach of the OAuth trust model and can damage platform reputation.
