CVE-2025-4389
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Crawlomatic Multipage Scraper Post Generator plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the crawlomatic_generate_featured_image() function in all versions up to, and including, 2.6.8.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

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.
-
Identify if Crawlomatic plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for a folder containing 'crawlomatic' in the name, or list all installed plugins via WP-CLI: wp plugin list --status=active --format=csvAffected if The plugin folder exists in the plugins directory and the plugin is active
-
Determine the installed plugin versionOpen the main plugin PHP file (usually crawlomatic.php or similar in the plugin folder) and locate the 'Version' header in the plugin comment block at the top, or run: grep -i 'Version:' /path/to/wp-content/plugins/crawlomatic*/*.php | head -5Affected if The version number is 2.6.8.1 or lower (any version up to and including 2.6.8.1)
-
Verify the vulnerable function existsSearch for the function name 'crawlomatic_generate_featured_image' in the plugin files: grep -r 'function crawlomatic_generate_featured_image' /path/to/wp-content/plugins/crawlomatic*/Affected if The function is found in the plugin code, indicating the vulnerable code path exists
-
Check for unauthorized uploaded filesInspect the WordPress uploads directory (wp-content/uploads/) for files with suspicious extensions (php, phtml, exe, js) that were uploaded without proper context, especially in date-based subdirectories: find /path/to/wp-content/uploads/ -type f -name '*.php' -mtime -30Affected if Unexpected script files (.php, .phtml) or other executable files appear in uploads directories, particularly those created after the plugin was installed and exposed
A user is affected if the Crawlomatic plugin is installed with version 2.6.8.1 or lower and the crawlomatic_generate_featured_image function is present in the code.

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 the plugin to the latest version once available. If no patch exists, disable the plugin or implement WAF rules to block unauthorized file uploads. Restrict or disable the affected function until patched.
2.6.8.2 or later
- 1. Log in to the WordPress admin dashboard
- 2. Navigate to Plugins > Installed Plugins
- 3. Locate the Crawlomatic Multipage Scraper Post Generator plugin
- 4. If an update is available, click 'Update Now' to update to the latest version
- 5. Alternatively, download the latest version from CodeCanyon and upload it via Plugins > Add New > Upload Plugin
- 6. After updating, verify the version number reflects the patched release
