The CVE-2025-24537 vulnerability is a Cross-Site Request Forgery (CSRF) issue found in StellarWP's The Events Calendar plugin for WordPress, affecting all versions up to and including 6.7.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unintended actions on behalf of the user. In this case, the vulnerability allows attackers to exploit the plugin's lack of proper CSRF token validation on certain state-changing requests. Since The Events Calendar is widely used for managing event data on WordPress sites, an attacker could potentially manipulate event creation, modification, or deletion by luring authenticated users to a malicious website. The vulnerability requires the victim to be authenticated on the target WordPress site but does not require any additional user interaction beyond visiting a crafted URL or page. No CVSS score has been assigned yet, and no public exploits have been reported. The absence of patch links indicates that a fix may still be pending or recently released. The vulnerability impacts the integrity and availability of event data managed by the plugin, potentially disrupting event operations or causing unauthorized data changes.

The primary impact of this CSRF vulnerability is on the integrity and availability of event data managed by The Events Calendar plugin. Attackers can cause authenticated users to unknowingly perform actions such as creating, modifying, or deleting events, which can disrupt business operations, cause misinformation, or damage reputations. For organizations relying heavily on event management for marketing, sales, or community engagement, such disruptions can lead to financial losses and reduced user trust. Since the vulnerability requires an authenticated user, the scope is limited to sites with logged-in users who have sufficient privileges to perform sensitive actions. However, given the popularity of WordPress and The Events Calendar plugin, a large number of websites worldwide could be at risk. The lack of known exploits reduces immediate risk, but the potential for automated or targeted attacks remains. Additionally, the vulnerability could be leveraged as part of a broader attack chain to escalate privileges or compromise site integrity.

Organizations should monitor for official patches from StellarWP and apply them promptly once available to remediate this CSRF vulnerability. In the interim, administrators can implement additional CSRF protections by ensuring that all state-changing requests in The Events Calendar plugin validate CSRF tokens properly. Web application firewalls (WAFs) can be configured to detect and block suspicious cross-site requests targeting the plugin's endpoints. Limiting user privileges to the minimum necessary reduces the risk of damage if an account is compromised. Educating users about the risks of clicking on untrusted links while authenticated can also help mitigate exploitation. Regularly auditing plugin versions and dependencies for vulnerabilities is recommended. If possible, temporarily disabling or restricting access to event management features until a patch is applied can reduce exposure. Monitoring logs for unusual activity related to event creation or modification can provide early detection of exploitation attempts.
