Introduction
Attackers with contributor-level access can seize administrator accounts on thousands of WordPress sites running Eventin, simply by changing an email address. This privilege escalation flaw, tracked as CVE-2025-4796, affects all Eventin plugin versions up to and including 4.0.34 and carries a CVSS score of 8.8.
About Eventin: Eventin is a widely used WordPress event management plugin developed by Themewinter, with over 10,000 active installations. It provides event scheduling, ticketing, and speaker management features for a broad range of organizations.
Technical Information
CVE-2025-4796 is rooted in the Eventin\Speaker\Api\SpeakerController::update_item function. This function is responsible for updating speaker details, including sensitive fields like email addresses. The vulnerability arises because the function does not properly validate the identity or capability of the user making the request. As a result, any authenticated user with contributor-level permissions or higher can submit a request that changes the email address of any user, including administrators.
The attack leverages a classic CWE-639 (Authorization Bypass Through User-Controlled Key) pattern. The vulnerable endpoint accepts a user-controlled identifier and does not enforce that the requester is authorized to update the targeted user's details. Once the attacker changes the email address of an administrator to one they control, they can use the standard WordPress password reset process to take over the account.

Proof of Concept
The vulnerability in the 'Element Pack Elementor Addons' plugin for WordPress, identified as CVE-2024-3925, allows authenticated users with contributor-level access or higher to inject malicious scripts into web pages. This is due to insufficient input sanitization and output escaping in the plugin's Creative Button widget, particularly through the 'onclick' event attribute.
An attacker can exploit this by crafting a payload that includes a malicious script within the 'onclick' attribute of the Creative Button widget. When this button is rendered on a page and clicked by a user, the embedded script executes in the context of the user's browser session. This could lead to various malicious outcomes, such as stealing session cookies, redirecting users to phishing sites, or performing actions on behalf of the user without their consent.
To mitigate this vulnerability, it is crucial to update the 'Element Pack Elementor Addons' plugin to version 5.6.8 or later, where the issue has been addressed. Additionally, implementing strict input validation and output escaping for all user-supplied data can help prevent similar vulnerabilities.

Patch Information
The developers of the Ai Auto Tool Content Writing Assistant (Gemini Writer, ChatGPT) All in One plugin have addressed a vulnerability related to missing authorization by implementing stricter access controls. This enhancement ensures that only users with appropriate permissions can access and modify sensitive information within the plugin. By enforcing these authorization checks, the risk of unauthorized data exposure is significantly reduced, thereby bolstering the overall security of the plugin.
Detection Methods
Detecting SQL Injection vulnerabilities, such as those present in the Smartrise Document Management System prior to version Hvl-2.0, requires a multifaceted approach. (nvd.nist.gov)
1. Log Analysis:
Regularly reviewing application and database logs can reveal anomalies indicative of SQL Injection attempts. Look for:
-
Unusual SQL Queries: Entries containing unexpected SQL commands or patterns, especially those with concatenated strings or unexpected keywords.
-
Error Messages: Repeated database error messages in logs may suggest exploitation attempts.
2. Web Application Firewalls (WAFs):
Implementing a WAF can help detect and block malicious SQL Injection payloads in real-time. WAFs analyze incoming traffic and can identify patterns associated with SQL Injection attacks.
3. Code Review and Static Analysis:
Conducting thorough code reviews and utilizing static analysis tools can identify potential vulnerabilities in the codebase. Focus on:
-
Input Validation: Ensure all user inputs are properly sanitized and validated.
-
Use of Parameterized Queries: Verify that database queries use parameterized statements to prevent injection.
4. Intrusion Detection Systems (IDS):
Deploying an IDS can help monitor network traffic for signs of SQL Injection attacks. IDS can be configured to alert administrators when suspicious activity is detected.
5. Regular Security Assessments:
Performing regular security assessments, including penetration testing, can help identify and remediate SQL Injection vulnerabilities before they can be exploited.
By integrating these detection methods, organizations can enhance their ability to identify and mitigate SQL Injection vulnerabilities, thereby strengthening their overall security posture.

Affected Systems and Versions
- Eventin WordPress plugin, all versions up to and including 4.0.34
- Any WordPress installation with Eventin <= 4.0.34 is vulnerable if contributor-level or higher users exist
Vendor Security History
Themewinter has experienced multiple critical vulnerabilities in the Eventin plugin in 2025. CVE-2025-47539 (unauthenticated privilege escalation) was patched in version 4.0.27. The recurrence of authorization flaws in subsequent versions (up to 4.0.34) suggests ongoing issues with secure development practices and code review.
