What is CVE-2026-81655?
The Ad Inserter plugin for WordPress fails to properly restrict access to one of its settings pages, allowing any logged-in user to access it under certain configurations. Additionally, the plugin lacks adequate content filtering for entries saved within this page, which enables users with minimal access rights (such as subscribers) to insert arbitrary code. This code can then be executed as PHP or delivered unescaped to site visitors, posing significant security risks.
Affected Version(s)
Ad Inserter 2.8.12 < 2.8.19
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.
