What is CVE-2026-118182?
The Duplicate Post plugin for WordPress versions prior to 1.5.8 contains a serious access control vulnerability. It fails to verify if a user attempting to duplicate a post has sufficient permissions to edit the original content. When the slug takeover feature is activated, this oversight enables users with limited roles, such as Contributors, to hijack existing posts by publishing their duplicate versions at the original post's URL. This poses a significant risk to content integrity and site security.
Affected Version(s)
Duplicate Post 0 < 1.5.8
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
