CVE-2026-93904 Details

A SQL injection vulnerability has been identified in the Social Web Suite – Social Media Auto Post, Social Media Auto Publish plugin for WordPress, affecting all versions through 4.1.12. The vulnerability arises from inadequate escaping of user-supplied data in the 'exclude_posts' parameter, coupled with insufficient preparation of the SQL query. This flaw allows unauthenticated attackers to inject additional SQL commands into existing queries, potentially leading to the extraction of sensitive information from the database. Furthermore, on newly activated installations where the administrator has not yet accessed the settings page, the HMAC authentication gate for the affected endpoint can be bypassed. This is because the secret_key option is empty until it is generated at that point, enabling an attacker to create a valid token using hash_hmac('sha256', '', $timestamp) with any chosen timestamp.
