CVE-2025-59819
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 · uneditedThis vulnerability allows authenticated attackers to read an arbitrary file by changing a filepath parameter into an internal system path.
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 confidenceThis is an authenticated path traversal (directory traversal) vulnerability allowing attackers to read arbitrary files on the system by manipulating a filepath parameter to point to internal system paths instead of intended directories.

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 access endpointsSearch application code and API definitions for functions that accept a filepath, file path, path, or similar parameter name for reading or serving filesAffected if The application processes a filepath parameter to access files on the system
-
Verify authentication requirementConfirm that file access endpoints require valid authentication (session token, API key, login credentials)Affected if File path endpoints are accessible without authentication (this would make it unauthenticated traversal, a more severe case)
-
Inspect path validation logicReview code that handles filepath parameters to see if it performs path canonicalization (resolving realpath or using os.path.realpath) and boundary checksAffected if No canonicalization or directory boundary validation is performed before using the filepath parameter
-
Check for traversal sequence filteringSearch code for filtering or rejection of ../ or ..\ sequences in filepath inputs, or look for allowlist validationAffected if Filepath parameters accept path traversal sequences without rejection or sanitization
-
Test for traversal vulnerabilityIf authorized, send a request with ../../etc/passwd or similar path traversal pattern in the filepath parameter and observe if arbitrary file contents are returnedAffected if The application returns contents of files outside the intended directory
The environment is affected if the application processes a filepath parameter for file access without proper path canonicalization and traversal sequence filtering.

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 using path canonicalization - resolve the full path and verify it stays within the intended base directory before allowing file access. Reject any input containing path traversal sequences (../ or ..\).
