CVE-2025-10749
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 Microsoft Azure Storage for WordPress plugin for WordPress is vulnerable to Unauthorized Arbitrary Media Deletion in all versions up to, and including, 4.5.1. This is due to missing capability checks on the 'azure-storage-media-replace' AJAX action. This makes it possible for authenticated attackers with subscriber-level access and above to delete arbitrary media files from the WordPress Media Library via the replace_attachment parameter granted they can access the nonce which is exposed to all authenticated users.
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 Microsoft Azure Storage for WordPress plugin versions up to 4.5.1 lack capability checks on the 'azure-storage-media-replace' AJAX action. Authenticated users with subscriber-level access can delete arbitrary media files from the WordPress Media Library by exploiting the exposed nonce and using the replace_attachment parameter.

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 Azure Storage plugin is installedGo to WordPress admin > Plugins and look for 'Microsoft Azure Storage for WordPress' or check the plugins directory for azure-storage folderAffected if The plugin is installed and active
-
Check the installed plugin versionIn WordPress admin > Plugins, click on the Microsoft Azure Storage plugin to view its version. Compare against 4.5.1Affected if Version is 4.5.1 or lower
-
Check if AJAX functionality is accessible to lower-privileged usersInspect the plugin PHP files for the 'azure-storage-media-replace' AJAX action hook and verify if current_user_can() or capability checks are missing before processing the requestAffected if The AJAX action exists and lacks proper capability checks for the replace_attachment functionality
-
Verify if subscriber-level accounts existIn WordPress admin > Users, review the list of existing user roles. Check if any users have the Subscriber roleAffected if Subscriber or other low-privilege user accounts exist in the WordPress installation
If the Microsoft Azure Storage for WordPress plugin versions 4.5.1 or lower is installed and active with the vulnerable AJAX action exposed, any authenticated user with Subscriber-level access can delete arbitrary media files.

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 · scopedApply the latest plugin update which adds proper capability checks to the AJAX action. Until then, disable or restrict the plugin's AJAX functionality for lower-privileged users, or disable the plugin entirely if immediate patching is not feasible.
