What is CVE-2026-16250?

The Personal QR Message WordPress plugin versions through 1.0 lacks proper restriction on file types that users can upload via an unauthenticated handler. This oversight permits unauthenticated users to upload arbitrary PHP executables, which can be directly accessed. If exploited, this could lead to unauthorized remote code execution, posing significant risks to the integrity and security of the affected WordPress installations.

Affected Version(s)

Personal QR Message 0 <= 1.0

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.
