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.
-
Check Happyforms plugin versionIn WordPress admin, go to Plugins > Installed Plugins and find Happyforms, or check the version in the plugin's main PHP file (happyforms.php) in wp-content/plugins/happyforms/Affected if The installed version is lower than 1.26.1 (e.g., 1.26.0, 1.25.x, etc.)
