CVE-2025-14943 Overview
CVE-2025-14943 affects the Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress in all versions up to and including 8.7.2. The vulnerability resides in the getShipItemFullText function, which performs an incomplete authorization check. The function validates that a requester holds the read capability and supplies a valid nonce, but it does not confirm whether the requester is permitted to access the specific post being queried. Authenticated users with Subscriber-level access or higher can exploit this flaw to read content from password-protected, private, or draft posts. The issue is classified under CWE-863: Incorrect Authorization.
Critical Impact
Authenticated attackers at Subscriber level can extract content from password-protected, private, and draft posts on affected WordPress sites.
Affected Products
- Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress
- All versions up to and including 8.7.2
- WordPress sites with Subscriber-level user registration enabled

Technical Details for CVE-2025-14943
Vulnerability Analysis
The Blog2Social plugin exposes an AJAX endpoint backed by the getShipItemFullText function defined in includes/Ajax/Get.php. The function returns the full text of a specified post so the plugin can prepare content for social media scheduling. Authorization logic in the handler relies on two checks: a WordPress capability check for the read capability and a nonce verification. The read capability is granted to every authenticated role, including the lowest privileged Subscriber role.
Neither check ties the requesting user to the post identifier supplied in the request. As a result, an authenticated user can submit any post_id value and receive the post body, including drafts that have never been published, posts marked private, and posts shielded by a password. This contradicts the WordPress access control model, which expects per-object capability checks such as current_user_can( 'read_post', $post_id ) before returning restricted content.
Root Cause
The root cause is a missing object-level authorization check [CWE-863]. The code path verifies user-level capability and request authenticity through the nonce, but omits the per-post permission check that WordPress provides for password-protected, private, and draft visibility states.
Attack Vector
Exploitation requires the attacker to hold a valid authenticated session with at least Subscriber privileges and to obtain a valid plugin nonce, which is exposed to authenticated users in plugin-rendered pages. The attacker issues an authenticated AJAX POST request to the plugin endpoint, specifying the target post_id. The server returns the full post text regardless of the post's visibility state or password protection. No user interaction is required from the post owner or any administrator.
The vulnerability does not allow modification of post data and does not affect availability. Impact is limited to confidentiality of post content. See the Wordfence Vulnerability Report and the WordPress Plugin Code Reference for the affected source.
Detection Methods for CVE-2025-14943
Indicators of Compromise
- Unexpected AJAX requests to the Blog2Social plugin endpoint referencing getShipItemFullText originating from low-privilege user sessions.
- Access log entries showing Subscriber-level accounts issuing repeated POST requests with varying post_id parameters.
- Newly registered Subscriber accounts that immediately interact with plugin AJAX endpoints.
Detection Strategies
- Review WordPress access logs for POST requests to admin-ajax.php with the action=getShipItemFullText parameter from non-editor accounts.
- Correlate authenticated session identifiers against accessed post_id values to detect users retrieving posts they do not own or cannot publicly read.
- Audit user role assignments and flag Subscriber accounts that query plugin endpoints associated with content retrieval.
Monitoring Recommendations
- Enable verbose logging on the WordPress application layer and forward events to a centralized analytics platform for query and alerting.
- Alert on authenticated requests to plugin AJAX actions that return HTTP 200 responses containing draft or private post identifiers.
- Track creation of new low-privilege accounts and subsequent enumeration patterns against post IDs.
How to Mitigate CVE-2025-14943
Immediate Actions Required
- Update the Blog2Social plugin to a version later than 8.7.2 once the vendor publishes a fix.
- Disable open user registration or restrict the default new-user role to a custom role without the read capability where feasible.
- Audit existing Subscriber accounts and remove any that are unrecognized or inactive.
Patch Information
The vendor revision history is tracked in the WordPress Plugin Revision History. Administrators should monitor the plugin changelog and the Wordfence Vulnerability Report for the fixed release that introduces a per-post authorization check on getShipItemFullText.
Workarounds
- Temporarily deactivate the Blog2Social plugin on sites that allow public user registration until a patched release is installed.
- Apply a web application firewall rule that blocks action=getShipItemFullText requests from accounts below Editor role.
- Restrict access to wp-admin/admin-ajax.php through server-level controls where business workflows permit.
# Example WordPress CLI commands to reduce exposure
wp plugin deactivate blog2social
wp option update users_can_register 0
wp user list --role=subscriber --fields=ID,user_login,user_registered
