Hackers exploit OttoKit WordPress plugin to create rogue admins

Summary

An authentication bypass in OttoKit

OttoKit, formerly SureTriggers, is a WordPress automation plugin that connects sites to other apps and services. A flaw tracked as CVE-2025-3102 lets attackers create administrator accounts without credentials on vulnerable sites.

Which sites are at risk

The plugin is installed on more than 100,000 sites. The bug only bites when the plugin is active but has no API key configured, and in that state a missing check lets an attacker pass authentication with an empty value. Then they create an admin.

How the flaw came to light

The flaw was found by researcher Michael Mazzolini and reported through Wordfence’s bug bounty program. A fix shipped on April 3, 2025. Attackers started trying to exploit it within hours of public disclosure, according to security firm Patchstack.

What attackers do with it

Attackers send crafted requests to the plugin’s REST endpoint to create new administrator accounts. Admin rights mean everything: malicious plugins, changed content, stolen data or backdoors that sit unnoticed for months.

What site owners should do

Update OttoKit to version 1.0.79 or later. Then check the site’s user list for administrator accounts you did not create, and review recent plugin installs.

Ongoing hygiene

Keep plugins updated and remove ones you no longer use. Keep restorable backups.

Lessons from OttoKit

The speed of exploitation is the lesson. Attackers watch vulnerability disclosures and move within hours, so sites that wait days to update are exposed.

Turning on automatic updates for trusted plugins is the simplest defense.
