What is CVE-2026-107120?

The Contest Gallery WordPress plugin prior to version 33.0.1 is vulnerable to a brute-force attack during its front-end registration email-verification process. This vulnerability occurs due to the absence of restrictions on the number of attempts to enter a short numeric PIN. As a result, unauthenticated attackers can exploit this weakness to repeatedly guess the PIN, enabling them to create and activate a WordPress account associated with an email address they do not control, thereby gaining unauthorized access to the system.

Affected Version(s)

Contest Gallery 0 < 33.0.1

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.
