AI Threat Summary
CVE-2026-93904 is a high-severity vulnerability with a CVSS score of 7.5 affecting the target software. This vulnerability allows SQL injection leading to unauthorized data access. Authentication can be bypassed allowing unauthenticated access. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.
Description
The Social Web Suite – Social Media Auto Post, Social Media Auto Publish plugin for WordPress is vulnerable to generic SQL Injection via the 'exclude_posts' parameter in all versions up to, and including, 4.1.12 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The HMAC authentication gate protecting the endpoint is bypassable on any freshly activated installation where an administrator has not yet visited the settings page, because the secret_key option remains empty until lazily generated at that point, allowing an attacker to compute a valid token using hash_hmac('sha256', '', $timestamp) with any chosen timestamp.
Attack Chain
Attacker fingerprints web application and identifies injectable parameters using automated scanners
Attacker injects SQL payload via vulnerable parameter to bypass authentication or extract data
Attacker dumps database tables including user credentials, session tokens, and sensitive data
Extracted password hashes cracked offline using hashcat/john or plain-text credentials used directly
Valid credentials reused across other systems and services in the environment
MITRE ATT&CK Techniques
SQL injection exploited against web application database layer
Database contents exfiltrated including credentials and PII
Credentials stolen from database used for further access
