  • Researcher: Dhabaleshwar Das
  • Description: The Events Calendar plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.3.0. This vulnerability stems from missing or incorrect nonce validation in the maybe_dismiss() function, allowing unauthenticated attackers to dismiss notices through forged requests if they can trick a site administrator into clicking a link.


The Events Calendar for WordPress has a vulnerability in versions up to and including 6.3.0 that allows unauthenticated attackers to forge requests to dismiss admin notices. This vulnerability has been patched in version 6.3.1.

Detailed Overview:

The vulnerability identified by researcher Dhabaleshwar Das involves a Cross-Site Request Forgery (CSRF) in The Events Calendar plugin. Specifically, the flaw is in the maybe_dismiss() function, which fails to properly validate nonces. This oversight means that attackers could manipulate site administrators into performing actions without their consent, such as dismissing important administrative notices that could contain security warnings or updates. While the direct impact on site integrity from this specific CSRF is limited to notice dismissal, the vulnerability highlights potential risks in nonce handling that could be exploited more maliciously if not addressed.

Advice for Users:

  • Immediate Action: Update to version 6.3.1 immediately to apply the security fix.
  • Check for Signs of Vulnerability: Review administrative actions logs to ensure no unauthorized changes have been made, especially dismissed notices around the time of vulnerability exposure.
  • Alternate Plugins: If you're concerned about ongoing security, consider evaluating alternative event management plugins that may have a stronger track record in security practices.
  • Stay Updated: Regular updates are crucial. Ensure that your plugins, themes, and core WordPress software are always up to date to protect against known vulnerabilities.


The quick response by The Events Calendar developers to address this CSRF vulnerability emphasizes the importance of rapid update deployment in the realm of cybersecurity. Users are advised to install version 6.3.1 or later to ensure their WordPress installations remain secure against this type of exploit.


Detailed Report: 

In today's fast-paced digital environment, the security of your website is paramount. This importance is only heightened for users of popular platforms like WordPress, where plugins enhance functionality but can also pose significant security risks if not properly managed. A recent example is the vulnerability found in The Events Calendar, a widely-used plugin that manages events seamlessly across WordPress sites. Identified as CVE-2024-31433, this vulnerability exposes websites to Cross-Site Request Forgery (CSRF), potentially allowing attackers to manipulate site administrators into unknowingly performing actions that compromise site security.

This vulnerability serves as a stark reminder of the dangers of outdated software. With over 700,000 active installs and a substantial user base reliant on its functionalities, The Events Calendar's recent issue underscores a critical aspect of web management—keeping software up to date is not just best practice; it's a necessity. As the digital landscape evolves, so too do the tactics of those looking to exploit any vulnerabilities, making regular updates an essential defense against potential attacks.

Vulnerability Details and Risks:

The vulnerability identified by researcher Dhabaleshwar Das involves a CSRF issue, specifically within the maybe_dismiss() function, which fails to properly validate nonces. This oversight can allow unauthenticated attackers to dismiss critical notices via forged requests. This not only misleads administrators about the current state of the site but could also lead to overlooked security warnings that are vital for maintaining the site's integrity.

Impact of the Vulnerability:

While the direct impact of this CSRF vulnerability primarily concerns the dismissal of notices, its existence can lead to broader security lapses if administrative warnings are not heeded or critical updates are missed. For a small business, this could translate into compromised user data or a tarnished reputation should the exploitation result in a noticeable breach.

Steps for Remediation:

  1. Update Immediately: Ensure that The Events Calendar plugin is updated to version 6.3.1, which contains the necessary fix.
  2. Review and Audit: Check the administrative actions log for any signs of unauthorized changes, especially related to notice dismissals.
