CVE-2026-12123
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 All-in-One Video Gallery plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.8.5 via the 'vdl' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. A Subscriber-level attacker can plant an internal or loopback URL in the `mp4` post meta of a newly created `aiovg_videos` post via XML-RPC `wp.newPost`, then trigger the unauthenticated `?vdl=<post_id>` endpoint to force the server to fetch that URL and stream the full response body back to the requester.
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 All-in-One Video Gallery WordPress plugin versions up to 4.8.5 contain an authenticated SSRF vulnerability via the 'vdl' parameter. Attackers with subscriber-level access can use XML-RPC to inject a malicious URL into post metadata, then trigger the vulnerable endpoint to force the server to fetch and return arbitrary internal/loopback URLs.

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 versionLocate the plugin's main file (e.g., all-in-one-video-gallery.php) in wp-content/plugins/ and read the version header, or query the WordPress database: SELECT option_value FROM wp_options WHERE option_name = 'active_plugins' and check plugin file headersAffected if The installed version is 4.8.5 or lower
-
Confirm XML-RPC is enabledAccess the XML-RPC endpoint at /xmlrpc.php and verify it responds (or check via WordPress admin > Settings > Writing > XML-RPC), or test with a pingback requestAffected if XML-RPC is enabled and accepts requests
-
Check for subscriber-level user accountsQuery the WordPress users table: SELECT user_login, user_email FROM wp_users WHERE ID IN (SELECT user_id FROM wp_usermeta WHERE meta_key = 'wp_capabilities' AND meta_value LIKE '%subscriber%')Affected if At least one subscriber-level user account exists
-
Identify vulnerable endpoint usageReview server access logs for requests to the plugin's endpoints containing the 'vdl' parameter, or examine the plugin source code for the handler that processes the 'vdl' parameter in post metadataAffected if The plugin processes 'vdl' parameter values from post metadata without validating whether they point to internal/loopback addresses
A user is affected if the All-in-One Video Gallery plugin version is 4.8.5 or lower AND XML-RPC is enabled AND at least one subscriber-level user account exists, allowing injection of malicious URLs via the 'vdl' parameter to trigger SSRF.

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 a patched version (4.8.6 or higher), or implement server-side validation to reject internal/loopback IP addresses and restrict URL schemes in the 'vdl' parameter processing.
