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.
-
Confirm WP Symposium plugin is installedLocate the WP Symposium plugin directory in the WordPress plugins folder (typically wp-content/plugins/). Verify the plugin files exist, specifically looking for a plugin named 'wpsymposiumpro' or 'wp-symposium'.Affected if The plugin directory exists and contains WP Symposium files.
-
Identify the installed versionCheck the plugin's version by opening the readme.txt file in the plugin directory, or view the plugin header comment in the main PHP file. The affected version is 13.04.Affected if The installed version is exactly 13.04.
-
Locate the invite.php scriptFind the invite.php file within the WP Symposium plugin directory structure.Affected if The invite.php file exists in the plugin directory.
-
Examine the 'u' parameter handlingOpen invite.php and search for code that processes the 'u' parameter. Look for redirect or header functions that use the 'u' parameter without validation, such as wp_redirect($_GET['u']) or similar patterns.Affected if The 'u' parameter is used in a redirect without sanitization or allowlist validation.
-
Verify open redirect is exploitableTest by requesting invite.php?u=http://example.com (where example.com is an external domain). If the response redirects to the external domain without validation, the vulnerability is present.Affected if The application redirects to the arbitrary URL provided in the 'u' parameter.
A user is affected if the WP Symposium plugin version 13.04 is installed with the invite.php file present and the 'u' parameter allows unvalidated redirects to external domains.

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.
From vendor dataUpgrade to a patched version of WP Symposium or remove the plugin if unmaintained. Implement server-side validation of the 'u' parameter to restrict redirects to trusted domains or relative paths only.
