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 Simple Documentation plugin is installedAccess your WordPress admin panel, navigate to Plugins > Installed Plugins, and search for 'Simple Documentation' or 'Simple Docs'. Confirm the plugin is present and activated.Affected if The plugin is installed and active in the WordPress environment.
-
Check installed plugin versionIn the Plugins list, locate Simple Documentation and view the version number displayed beneath the plugin name. Compare this against the affected range: any version <= 1.2.8 is vulnerable.Affected if The installed version number is 1.2.8 or lower.
-
Identify state-changing admin actionsReview the plugin admin interface for features that accept and store user input, such as creating/editing documentation pages, managing categories, or saving settings. These are the endpoints where XSS payload injection could occur.Affected if The plugin provides admin-facing forms or interfaces that accept user input and store it for later display.
-
Confirm absence of CSRF token protectionInspect the HTML source of the plugin admin forms. Look for a hidden input field containing a CSRF token (commonly named '_wpnonce', 'nonce', 'csrftoken', or similar) and verify the form submits this token with the request.Affected if The plugin forms lack CSRF token fields, or the submitted requests do not validate tokens server-side.
If Simple Documentation plugin is installed with version 1.2.8 or lower and exposes admin forms without CSRF token protection, the environment is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 patched version when available; otherwise implement anti-CSRF tokens for all state-changing operations and apply proper input sanitization and output encoding to prevent stored XSS.
Latest version of Simple Documentation (vendor repository) - any version higher than 1.2.8
- 1. Update the Simple Documentation plugin to the latest available version from the WordPress plugin repository or the vendor's official source
- 2. Verify the update was successful by checking the plugin version in the WordPress admin panel
- 3. Test the plugin functionality to ensure the update did not break existing features
- 4. Clear any cache if the site uses caching plugins
- 5. Consider running a security scan to confirm the vulnerability is resolved
