What the vulnerability does
01Description
The Page and Post Clone plugin for WordPress is vulnerable to SQL Injection via the 'meta_key' parameter in the content_clone() function in all versions up to, and including, 6.3. This is due to insufficient escaping on the user-supplied meta_key value and insufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection is second-order: the malicious payload is stored as a post meta key and executed when the post is cloned.
Explanation of Vulnerability in Simple Terms
02Summary
Fast Page & Post Duplicator versions 6.3 and earlier contain a SQL injection vulnerability in a component requiring low-level authentication. An authenticated attacker can craft malicious input to execute arbitrary SQL queries, potentially reading sensitive data from the site's database. Update to a version newer than 6.3 to resolve this issue.
