CVE-2025-6065
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 Image Resizer On The Fly plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'delete' task in all versions up to, and including, 1.1. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Image Resizer On The Fly WordPress plugin lacks proper file path validation in its 'delete' function, allowing unauthenticated attackers to manipulate file paths and delete arbitrary files on the server. This arbitrary file deletion vulnerability has a critical severity (CVSS 9.1) because deletion of critical files like wp-config.php can lead to complete site compromise and remote code execution.

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 plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Image Resizer On The Fly' or check the /wp-content/plugins/ directory for a folder matching this plugin name. Note the installed version number.Affected if The plugin is present in the WordPress installation regardless of version, as the specific vulnerable version range is not provided.
-
Confirm delete functionality is accessibleExamine the plugin code for an AJAX endpoint or direct URL handler that triggers the 'delete' function. Look for files containing 'delete' in the filename or function calls like wp_ajax_* or wp_ajax_nopriv_* related to deletion. Test if the delete action responds without authentication.Affected if The delete function is exposed and accessible without authentication.
-
Check for missing path validationReview the plugin source code for the delete function. Look for code that accepts a file path parameter without sanitizing it with functions like realpath(), basename(), or path traversal checks (such as checking for '../' or absolute paths).Affected if The delete function accepts user-supplied paths without validating they fall within an allowed directory.
-
Inspect for signs of compromiseCheck if wp-config.php, .htaccess, or other critical WordPress files have been deleted or modified. Look in the WordPress root directory for missing files. Review server access logs for unusual delete requests to the plugin endpoint.Affected if Critical files are missing, modified, or access logs show suspicious delete requests to the plugin.
-
Verify file permissionsCheck the permissions on the wp-content/uploads directory and other writable directories. The vulnerability requires write access to the directories where files can be deleted.Affected if The web server user has write permissions to sensitive directories that could be targeted.
You are affected if the Image Resizer On The Fly plugin is installed AND its delete function is exposed without authentication, regardless of version since specific patched version details were not provided.

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 the plugin to the latest patched version immediately. If no patch is available, remove the plugin or disable the affected delete functionality. Consider file permission restrictions as an interim control.
