CVE-2026-108092: 
WordPress Analisi e mitigazione delle vulnerabilità

CVE-2026-108092 is an authorization bypass vulnerability in the WordPress "Social Media Auto Post & Scheduler" plugin (Blog2Social by Adenion), affecting all versions up to and including 9.1.4. The flaw allows authenticated attackers with Contributor-level access or above to read titles and content of other users' private and pending posts. The CVE status is currently listed as "Reserved," and the vulnerability is estimated to be of MEDIUM severity (Feedly, VulDB).

The root cause is a missing per-object authorization check (CWE-639: Authorization Bypass Through User-Controlled Key) in the b2s_ship_item and b2s_ship_item_reload_url AJAX handlers. These handlers accept a postId parameter that is not validated against the requesting user's ownership or access rights, allowing any authenticated user to supply an arbitrary post ID and retrieve its content. This means a Contributor-level user can enumerate post IDs and access private or pending posts belonging to other users without any additional privileges (Feedly, Offseq Radar).

Successful exploitation results in unauthorized disclosure of confidential post content, including titles and body text of private and pending posts authored by other users on the same WordPress installation. This represents a confidentiality breach that could expose unpublished editorial content, sensitive drafts, or private communications stored as posts. Integrity and availability are not directly impacted, but the exposed content could be leveraged for competitive intelligence, social engineering, or reputational harm (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported at this time. Exploitation requires an authenticated account with at least Contributor-level access to the target WordPress site, limiting the attack surface compared to unauthenticated vulnerabilities. No EPSS score or CISA KEV catalog listing has been identified for this CVE (Feedly, VulDB).

1. Reconnaissance: Identify a WordPress site running the Blog2Social (Social Media Auto Post & Scheduler) plugin version 9.1.4 or earlier. Confirm the plugin is active by checking for plugin-specific assets or admin menu items.
2. Obtain Contributor Access: Register or log in as a Contributor-level (or higher) user on the target WordPress site.
3. Enumerate Post IDs: Use WordPress's predictable sequential post ID scheme to enumerate potential post IDs (e.g., starting from 1 and incrementing).
4. Craft Malicious AJAX Request: Send an authenticated HTTP POST request to the WordPress AJAX endpoint (/wp-admin/admin-ajax.php) targeting the b2s_ship_item or b2s_ship_item_reload_url action, supplying an arbitrary postId value corresponding to a private or pending post.
5. Extract Content: Parse the AJAX response to retrieve the title and content of the targeted post, which is returned without authorization validation (Feedly, Offseq Radar).

• Logs: WordPress access logs showing repeated authenticated POST requests to /wp-admin/admin-ajax.php with action=b2s_ship_item or action=b2s_ship_item_reload_url and sequentially incrementing or varied postId values from a single user account.
• Logs: Unusual access patterns where a Contributor-level account is making a high volume of AJAX requests to Blog2Social handlers outside of normal posting activity.
• Network: Automated or scripted HTTP POST traffic to the WordPress AJAX endpoint with Blog2Social-specific action parameters from a single source IP.

WordPress site administrators should update the Blog2Social plugin to a version beyond 9.1.4 once a patched release is made available by the vendor (Adenion). In the interim, consider restricting Contributor-level user registration or temporarily deactivating the Blog2Social plugin if untrusted contributors have access to the site. Monitoring AJAX logs for anomalous access patterns targeting the affected handlers is also recommended as a detective control (Feedly, VulDB).
