CVE-2025-9807
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe The Events Calendar plugin for WordPress is vulnerable to time-based SQL Injection via the ‘s’ parameter in all versions up to, and including, 6.15.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Events Calendar WordPress plugin versions up to 6.15.1 contains a time-based SQL injection vulnerability in the 's' parameter. The vulnerability stems from insufficient escaping of user-supplied input combined with lack of prepared statements in the existing SQL query, allowing unauthenticated attackers to inject arbitrary SQL and extract sensitive database information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify the Events Calendar plugin is installedNavigate to WordPress Admin > Plugins and look for 'The Events Calendar' in the installed plugins list, or use WP-CLI: wp plugin list --name='the-events-calendar'Affected if The plugin is present in the installation
-
Check the installed plugin versionIn WordPress Admin > Plugins, click on the Events Calendar plugin to view its version number, or run: wp plugin get the-events-calendar --field=versionAffected if Version is 6.15.1 or lower (any version up to and including 6.15.1)
-
Confirm the search feature is accessibleTest if the search parameter 's' is processed by visiting a frontend page on the site and using the search functionality (e.g., /?s=test), or check if the events calendar includes search-enabled templatesAffected if The site's events calendar pages accept and process the 's' query parameter
-
Identify if the site uses vulnerable plugin code patternsIf you have file access, examine the plugin file that handles search queries (typically in the plugin's common/template files) for direct use of the 's' parameter in SQL queries without prepare() statements; otherwise, this requires source code reviewAffected if Custom code or templates directly use $_GET['s'] or similar in SQL without prepared statements
You are affected if the Events Calendar plugin version is 6.15.1 or lower AND the site uses the search functionality that processes the 's' parameter.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate to version 6.15.2 or later to patch the SQL injection vulnerability. If immediate patching is not possible, consider disabling the plugin or implementing a Web Application Firewall (WAF) rule to filter malicious 's' parameter requests.
The Events Calendar version 6.15.2 or later
- 1. Log in to the WordPress admin dashboard
- 2. Navigate to Plugins > Installed Plugins
- 3. Locate 'The Events Calendar' plugin
- 4. If an update is available, click 'Update Now' to install the latest version
- 5. Alternatively, download the latest version from wordpress.org/plugins/the-events-calendar/ and upload via Plugins > Add New > Upload Plugin
- 6. After updating, verify the plugin is running version 6.15.2 or higher
