## What is CVE-2026-2893?

CVE-2026-2893 is a medium-severity SQL injection vulnerability in carlosfazenda Fast Page & Post Duplicator, published on 5 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
