What is CVE-2026-75860?

The JSON Options WordPress plugin prior to version 0.0.4 contains a significant security flaw that lacks proper capability checks and nonce verification. This oversight permits unauthenticated users to trigger actions that alter arbitrary WordPress options on every request. By exploiting this vulnerability, attackers can enable user registration and assign the default role as administrator, ultimately allowing them to gain full control over the WordPress site.

Affected Version(s)

JSON Options 0 <= 0.0.4

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.
