CVE-2025-54926
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 · uneditedCWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists that could cause remote code execution when an authenticated attacker with admin privileges uploads a malicious file over HTTP which then gets executed.
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 confidenceA path traversal vulnerability (CWE-22) in the file upload functionality allows an authenticated administrator to upload malicious files outside the intended restricted directory via HTTP. The uploaded file is subsequently executed, enabling 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.
-
Identify file upload functionalityReview application web routes and HTML forms to locate endpoints that accept file uploads. Look for multipart/form-data POST requests in your web server logs or application source code.Affected if File upload functionality exists and is accessible to authenticated administrators
-
Verify administrator authentication is requiredInspect the file upload endpoint's access controls. Attempt to access the upload functionality with a non-administrator account or without authentication to confirm privileges are enforced.Affected if The upload endpoint accepts requests from authenticated administrators but lacks proper path validation
-
Check upload directory configurationReview the web server and application configuration to identify the designated upload directory. Inspect the path handling code to see if user-supplied filenames are sanitized before file placement.Affected if Uploaded files can be placed outside the intended restricted directory using path traversal sequences (e.g., ../../../) in the filename
-
Verify execution permissions on upload directoryInspect file system permissions on the designated upload directory. Check if the directory allows execution of uploaded files or is located within a directory that permits script execution.Affected if Uploaded files can be placed in executable locations or directories that allow script execution
-
Confirm uploaded files are served with execute permissionsReview how the application serves uploaded files. Check if uploaded files are given executable permissions or are served as dynamic scripts rather than static content.Affected if The application executes uploaded files rather than serving them as static downloads
A user is affected if they have an authenticated administrator-accessible file upload endpoint that does not properly sanitize path traversal sequences in filenames and allows uploaded files to be placed in executable locations.

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 strict input validation and path sanitization on file upload endpoints to ensure uploaded files remain within designated directories and cannot be placed in executable locations. Restrict execution permissions on upload directories.
