What is CVE-2025-1627?

The Qi Blocks WordPress plugin, prior to version 1.4, fails to validate and escape certain block options before rendering them in pages or posts. This oversight can lead to stored cross-site scripting (XSS) vulnerabilities, allowing users with contributor roles and above to inject malicious scripts into the web application, potentially compromising user data and security.

Affected Version(s)

Qi Blocks 0 < 1.4

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.
