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 vulnerability was found in 666ghj MiroFish up to 0.1.2. This affects the function get_simulation_posts of the file backend/app/api/simulation.py of the component Query Parameter Handler. Performing a manipulation of the argument Platform results in path traversal. The attack can be initiated remotely. The exploit has been made public and could be used.

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 vulnerability exists in the get_simulation_posts function within backend/app/api/simulation.py of MiroFish up to version 0.1.2. The 'Platform' query parameter is not properly validated, allowing attackers to use directory traversal sequences (e.g., ../../) to access files outside the intended directory. This can lead to unauthorized file system access.

MitigationImplement strict input validation on the Platform parameter to reject path traversal sequences and normalize file paths to prevent directory escape. Use allowlists for permitted platform values and ensure file access is restricted to 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 checks

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

  1. Verify MiroFish installation and version
    Locate the MiroFish application and determine its installed version (e.g., check package.json, setup.py, or version file). Compare against the affected range: versions up to and including 0.1.2 are vulnerable.
    Affected if MiroFish version is 0.1.2 or lower, or version cannot be determined but the application is present.
  2. Locate the vulnerable source file
    Find the file backend/app/api/simulation.py in the MiroFish installation directory.
    Affected if The file exists in the installation, indicating the vulnerable code is present.
  3. Inspect the get_simulation_posts function for input validation
    Open backend/app/api/simulation.py and examine the get_simulation_posts function. Look for the 'Platform' query parameter handling to see if it performs validation, sanitization, or rejects path traversal sequences (../)
    Affected if The function reads the Platform parameter without rejecting or sanitizing '../' sequences, or lacks path traversal checks entirely.
  4. Check if the simulation API endpoint is exposed
    Identify if the /simulation or related API endpoint that uses get_simulation_posts is accessible (check routing configuration or API URLs).
    Affected if The API endpoint is publicly or internally accessible without additional access controls that would prevent parameter injection.
  5. Verify file access restrictions
    Review whether the application restricts file access to the intended directory or uses allowlisting for platform values.
    Affected if The Platform parameter can accept arbitrary paths or values without allowlisting, or file access is not restricted to a safe base directory.

A user is affected if MiroFish version 0.1.2 or lower is installed and the Platform parameter in the get_simulation_posts function accepts path traversal sequences without validation.
