CVE-2025-22213
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 · uneditedInadequate checks in the Media Manager allowed users with "edit" privileges to change file extension to arbitrary extension, including .php and other potentially executable extensions.
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 · moderate confidenceThe Media Manager component lacks proper input validation when handling file extension modifications, allowing authenticated users with edit privileges to change file extensions to executable types like .php. This insufficient validation could enable remote code execution if the modified files are subsequently accessed and executed by the server.

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.
-
Confirm Media Manager component is installedLocate the Media Manager component in your application - check for media management modules, libraries, or plugins used for handling file uploads and modifications in your web applicationAffected if The Media Manager component is present in the environment
-
Identify if edit/rename functionality existsReview the Media Manager features and locate any file renaming, file extension modification, or file properties editing capabilities available to usersAffected if File extension modification or renaming feature is exposed to users
-
Check authentication and authorization controlsVerify whether authenticated users with edit privileges can access the file extension modification feature - review user role permissions and access controls for the Media ManagerAffected if Authenticated users with edit privileges can modify file extensions
-
Inspect file extension validation logicExamine the code or configuration that handles file extension changes - look for input validation routines that accept or reject specific file extensions during rename/modify operationsAffected if No strict allowlist exists or executable extensions (.php, .exe, .js, etc.) are not explicitly blocked during extension changes
-
Test extension modification behaviorIf you have access to a test environment, attempt to rename a file to an executable extension (.php, .php5, .phtml, .exe, .js) through the Media Manager interface using an authenticated session with edit privilegesAffected if The system permits changing a file extension to an executable type without rejection
A user is affected if the Media Manager component is present and allows authenticated users with edit privileges to modify file extensions to executable types like .php without proper validation.

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 dataImplement a strict allowlist for permitted file extensions and block changes to executable extensions (.php, .exe, .js, etc.) in the Media Manager file renaming functionality.
