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 · moderate confidenceA CSRF vulnerability in the Fyrebox Quizzes WordPress plugin's shortcode functionality allows attackers to inject malicious JavaScript through stored XSS. The plugin fails to validate anti-CSRF tokens (nonces) when processing shortcode submissions, enabling authenticated attackers to trick administrators or users into executing unintended actions that store malicious scripts in quiz content.

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 Fyrebox Quizzes plugin is installedNavigate to WordPress admin > Plugins and confirm Fyrebox Quizzes is listed among installed pluginsAffected if Plugin is not installed indicates not affected
-
Identify installed plugin versionClick on the plugin in the WordPress plugins list to view version details, or check the plugin header in wp-content/plugins/fyrebox-quizzes/*.phpAffected if Unable to determine version - assume potentially affected if plugin is present
-
Confirm shortcode functionality is in useSearch WordPress posts/pages content for [fyrebox] shortcode usage, or check quiz settings where shortcodes may be embeddedAffected if Shortcode is actively used in site content - vulnerability requires shortcode processing to be exploitable
-
Inspect quiz content for suspicious scriptsReview quiz questions, results pages, and custom content fields in plugin settings for unexpected script tags, iframe elements, or event handlers (onclick, onerror, etc.)Affected if Any unknown or malicious JavaScript code found in quiz content indicates exploitation
-
Review recent user activity logsCheck WordPress audit logs or plugin activity logs for unexpected shortcode submissions or quiz content changes from untrusted usersAffected if Unauthorised changes to quiz content detected suggests active exploitation
You are affected if the Fyrebox Quizzes plugin is installed with shortcode functionality enabled and malicious scripts are found stored in quiz content or recent unauthorized changes to quiz settings are present.
