What is CVE-2026-78333?
The 12 Step Meeting List WordPress plugin prior to version 3.19.17 allows unauthenticated users to submit unsanitized input, which is stored in the activity log. This input is later displayed back to users in the admin area without adequate escaping, making it possible for an attacker to execute malicious scripts. Such attacks can target users with higher privileges, such as administrators, potentially compromising system integrity and security.
Affected Version(s)
12 Step Meeting List 3.17 < 3.19.17
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.
