dbcve checksWork through these to decide whether this CVE applies to you.
-
Check SureForms Pro plugin versionIn WordPress admin, go to Plugins > Installed Plugins > locate SureForms Pro and read the version number from the plugin description. Alternatively, check the main plugin file (e.g., wp-content/plugins/sureforms-pro/sureforms.php) for the 'Version' header comment.Affected if The installed version is lower than 2.8.1 (e.g., 2.8.0, 2.7.x, earlier versions)
