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
