Page and Post Clone, CVE-2026-2893

CVE, Research URL: CVE-2026-2893
Home page URL: Security reports for Page and Post Clone
Application: Page and Post Clone
Published on: Mar 05, 2026
Research 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.
Affected versions: max 6.4.
Status: vulnerable
