Intelligence Report: Attackers are exploiting recently disclosed OttoKit WordPress plugin flaw – Securityaffairs.com

1. BLUF (Bottom Line Up Front)

A critical vulnerability, CVE-2025-3102, in the OttoKit WordPress plugin, formerly known as SureTriggers, is being actively exploited. This flaw allows attackers to bypass authentication and create administrator accounts on unconfigured sites, leading to potential full site takeovers. Immediate updates to version 1.0.79 are strongly recommended to mitigate this risk.

2. Detailed Analysis

The following structured analytic techniques have been applied for this analysis:

General Analysis

The vulnerability in the OttoKit plugin is due to a missing empty value check on the ‘secret_key’ in the ‘authenticate_user’ function. This oversight allows attackers to create administrator accounts on WordPress sites where the plugin is installed but not configured with an API key. The flaw affects all versions up to 1.0.78 and is actively exploited, with over 100,000 sites potentially at risk. The vulnerability was discovered by Michael Mazzolini and has been patched in version 1.0.79.

3. Implications and Strategic Risks

The exploitation of this vulnerability poses significant risks to website integrity and user data security. It can lead to unauthorized access, data breaches, and the distribution of malware. The widespread use of the plugin amplifies the potential impact on national security, regional stability, and economic interests, particularly for businesses relying on WordPress for their online presence.

4. Recommendations and Outlook

Recommendations:

• Website administrators should immediately update the OttoKit plugin to version 1.0.79 to mitigate the vulnerability.
• Implement regular security audits and ensure all plugins are configured correctly with necessary API keys.
• Consider regulatory measures to enforce timely updates and security compliance for widely-used software.

Outlook:

In the best-case scenario, rapid adoption of the patch will minimize exploitation incidents. The worst-case scenario involves widespread exploitation leading to significant data breaches and financial losses. The most likely outcome is a gradual decline in exploitation attempts as more sites update to the secure version.

5. Key Individuals and Entities

The report mentions Michael Mazzolini as the researcher who discovered the vulnerability. The entities involved include Wordfence and PatchStack, which have confirmed active exploitation attempts.
