CF Internal Link Shortcode WordPress Plugin SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the CF Internal Link Shortcode plugin for WordPress, affecting all versions through 1.1.0. The issue arises from inadequate escaping of user-supplied data in the 'post_title' parameter, allowing unauthenticated attackers to inject additional SQL queries. This exploitation could lead to unauthorized access to sensitive information within the database.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to extract sensitive information from the database.

Reproduction

To reproduce this vulnerability, send a request to the WordPress site with the 'post_title' parameter included. The injected SQL payload can then be executed by the vulnerable SQL query in the plugin.

Remediation

No known patch is available. It is recommended to uninstall the affected plugin and consider a replacement.
