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 Uncanny Automator Pro is installedLocate the Uncanny Automator Pro plugin in your WordPress plugins directory, typically at /wp-content/plugins/uncanny-automator-pro/, and confirm the presence of the main plugin file (e.g., uncanny-automator-pro.php).Affected if The plugin is not installed.
-
Check the installed versionOpen the main plugin file and locate the version comment header (e.g., 'Version: x.x.x'), or check the plugin metadata via WordPress admin under Plugins > Installed Plugins. Compare the version number to 7.3.0.6.Affected if The installed version is 7.3.0.6 or lower.
-
Confirm PHP unserialize usage in plugin codeSearch the plugin source files for calls to unserialize() function, particularly in files handling user input or front-end submissions. Use grep or similar: grep -r "unserialize" /wp-content/plugins/uncanny-automator-pro/Affected if unserialize() calls exist that process user-supplied data without prior sanitization.
-
Identify if subscriber-level users can trigger the vulnerable inputReview user role capabilities in WordPress admin under Users > Roles, or check the Uncanny Automator Pro settings for any triggers or recipes that accept input from the 'Subscriber' role. Confirm whether subscriber users can create or trigger recipes.Affected if Subscriber-role users have permission to create or trigger automations that pass input to the vulnerable code path.
A user is affected if Uncanny Automator Pro version 7.3.0.6 or lower is installed, the plugin processes unserialize() on untrusted input, and subscriber-level users can trigger the vulnerable code path.

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.
From vendor dataUpdate Uncanny Automator Pro to a version newer than 7.3.0.6 immediately; if no patched version is available, consider disabling the plugin until a fix is released.
