What is CVE-2026-84899?

The VikWidgetsLoader plugin for WordPress prior to version 1.12.0 contains a significant code injection vulnerability. It fails to properly sanitize or escape a block attribute before including it in an inline script. This oversight allows users with Contributor permissions to insert arbitrary JavaScript into posts. As a result, any user who views the post, including administrators responsible for review, may inadvertently execute malicious scripts in their browsers, posing serious security risks.

Affected Version(s)

VikWidgetsLoader 1.11.0 < 1.12.0

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.
