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 Download Monitor plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Simple Download Monitor' by Tipsandtricks HQ, or check the /wp-content/plugins/simple-download-monitor directory existsAffected if Plugin is installed and active
-
Check installed plugin versionIn WordPress admin plugins list, find the version number listed under the Simple Download Monitor plugin, or open simple-download-monitor/readme.txt and check the version headerAffected if Version is 3.8.8 or lower (any version <= 3.8.8)
-
Confirm plugin is actively handling download requestsCheck if any download links on the site use the sdm_get_download shortcode or point to /?sdm_download= or similar download handlers - the plugin must be in use for the vulnerability to be reachableAffected if Plugin is active and serving download content via query parameters
-
Inspect web server logs for suspicious SQL injection patternsReview access logs for requests to the plugin's download endpoint containing SQL keywords (UNION, SELECT, INSERT, --, etc.) or unusual characters in the sdm_download parameterAffected if Log entries show SQL injection attempts targeting the plugin's download handler
