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
Frappe is a full-stack web application framework. Versions prior to 15.105.0 and 16.15.0 contain a possible Arbitrary File Read vulnerability via Path Traversal. The issue is resolved in versions 16.15.0, 15.105.0 and above.

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 confidence

Frappe framework versions prior to 15.105.0 and 16.15.0 contain an arbitrary file read vulnerability exploitable through path traversal. Attackers can manipulate file paths to access sensitive files outside the intended web root directory.

MitigationUpgrade Frappe to version 15.105.0 or 16.15.0 or later to resolve the path traversal vulnerability.

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 Frappe installation exists
    Run 'bench version' from the Frappe bench directory, or check pip show frappe, or look for Frappe installation in the system
    Affected if Frappe framework is installed on the server
  2. Identify the exact Frappe version
    Execute 'bench version' or 'pip show frappe' to retrieve the installed version number
    Affected if The version returned is lower than 15.105.0 or 16.15.0, or falls in the range between these major versions
  3. Confirm the file handling endpoint is exposed
    Check if web requests to file-related routes (such as /api/method/frappe... or file download endpoints) are reachable from the network without authentication
    Affected if The file handling functionality is accessible over the network without authentication
  4. Verify file operations are permitted
    Inspect whether the Frappe file handler allows arbitrary path traversal in request parameters (such as using ../ sequences in file path arguments)
    Affected if The file path input in the file handling functionality accepts and processes path traversal sequences

You are affected if Frappe is installed with a version prior to 15.105.0 or prior to 16.15.0 and the file handling functionality is accessible without authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Frappe to version 15.105.0 or 16.15.0 or later to resolve the path traversal vulnerability.

Recommended fix High confidence

15.105.0 (for v15.x) or 16.15.0 (for v16.x)

  1. 1. Identify the currently installed Frappe version by checking the requirements.txt, bench version, or site configuration
  2. 2. If running Frappe version 15.x, upgrade to version 15.105.0 or later
  3. 3. If running Frappe version 16.x, upgrade to version 16.15.0 or later
  4. 4. Run database migrations after upgrade using `bench migrate` or `bench --site [site-name] migrate`
  5. 5. Clear cache and restart all Frappe workers/services
  6. 6. Verify the upgrade was successful and test that the path traversal vulnerability is resolved
