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 · unedited
A security flaw has been discovered in geyang ml-logger up to acf255bade5be6ad88d90735c8367b28cbe3a743. Affected by this issue is the function stream_handler of the file ml_logger/server.py of the component File Handler. Performing manipulation of the argument key results in information disclosure. The attack can be initiated remotely. The exploit has been released to the public and may be exploited. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available.

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 confidence

A path traversal or insecure direct object reference vulnerability exists in the ml-logger's stream_handler function in ml_logger/server.py. By manipulating the 'key' argument, an attacker can access files or data they should not have access to, leading to information disclosure. The vulnerability is in the File Handler component and can be exploited remotely.

MitigationImplement proper authorization and input validation on the 'key' parameter in the stream_handler function to ensure users can only access resources they are authorized to view. Validate that the requested key matches the user's permissions before returning any file data.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check ml-logger package version
    Run 'pip show ml-logger' or 'pip list | grep ml-logger' to identify the installed version
    Affected if The installed version falls within any affected version range (compare to vendor-advisory versions when available)
  2. Locate the stream_handler source file
    Find ml_logger/server.py in your environment using 'find / -path "*/ml_logger/server.py" 2>/dev/null' or checking the package installation path
    Affected if The file exists and contains the stream_handler function definition
  3. Verify File Handler is enabled
    Check your ml-logger configuration files or initialization code for File Handler setup (look for 'stream_handler', 'file_handler', or similar handler configurations)
    Affected if File Handler component is configured and active in your deployment
  4. Inspect key parameter handling in stream_handler
    Examine the stream_handler function code in ml_logger/server.py - look for how the 'key' argument is processed and whether it is used in file path operations without validation
    Affected if The 'key' parameter is used directly in file operations (e.g., open(), os.path.join()) without proper sanitization or authorization checks
  5. Test for path traversal exposure
    If the endpoint is accessible, attempt a request with 'key' values like '../' or absolute paths to see if unauthorized file access is possible (e.g., '?key=../../../etc/passwd')
    Affected if The application returns file contents outside the intended directory or exposes sensitive files

You are affected if ml-logger with the vulnerable stream_handler is deployed, File Handler is enabled, and the 'key' parameter is not properly validated before use in file operations.

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.

Mitigation

Implement proper authorization and input validation on the 'key' parameter in the stream_handler function to ensure users can only access resources they are authorized to view. Validate that the requested key matches the user's permissions before returning any file data.
