CVE-2025-47539

What is CVE-2025-47539?

CVE-2025-47539 is a privilege escalation vulnerability identified in the Eventin plugin by Themewinter, which is commonly used within the WordPress ecosystem. The Eventin plugin is designed to manage events, including features for ticketing and event registration, making it a valuable tool for organizations that host events online. The vulnerability arises from an incorrect privilege assignment, allowing an attacker to gain elevated privileges within the application. This could lead to unauthorized modifications, data exposure, or even complete takeover of the affected system, severely impacting the organization's operations and data integrity.

The flaw affects versions up to and including 4.0.26 of the Eventin plugin, which is noteworthy as many organizations may still be utilizing older versions, potentially leaving them exposed. In environments where security protocols are critical, such as those handling sensitive event data or payment information, the exploitation of this vulnerability could have dire consequences, leading to significant financial and reputational damage.

Potential Impact of CVE-2025-47539

1. Unauthorized Access and Control: The primary risk associated with this vulnerability is the possibility for an attacker to escalate their privileges, granting them unauthorized access to restricted areas of the system. This could enable malicious users to alter event information, manipulate system settings, and access sensitive data.

2. Data Breaches: With the ability to gain elevated access, attackers could extract confidential data stored within the Eventin application, such as user information, payment details, and other sensitive event-related data. This could lead to significant data breaches, with legal and regulatory implications for affected organizations.

3. Operational Disruption: The exploitation of this vulnerability could lead to disruptions in the organization's event management processes, potentially causing cancellations or malfunctions in event registrations. This disruption can result in financial losses and a compromised reputation, especially in businesses reliant on the smooth operation of events.
