Summary

The InstaWP Connect plugin for WordPress contains a security flaw that allows for arbitrary option updates through unauthenticated access. This vulnerability arises from a lack of proper authorization checks during REST API calls, affecting all versions up to and including 0.1.0.38. Attackers exploiting this vulnerability can connect the affected WordPress site to InstaWP APIs, modify site options without authentication, and potentially create administrator accounts, posing significant risks to site integrity and security.

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.
