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
This vulnerability exists in Bagisto due to improper validation of user-supplied input in the ImageCacheController component. An unauthenticated remote attacker could exploit this vulnerability by sending crafted path traversal sequences through the filename parameter to access arbitrary files outside the intended directory on the targeted system. Successful exploitation of this vulnerability could allow an attacker to read arbitrary sensitive files on the targeted system.

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

This is a path traversal vulnerability in Bagisto's ImageCacheController where the filename parameter is not properly validated, allowing unauthenticated attackers to use crafted path traversal sequences (such as ../) to escape the intended directory and read arbitrary sensitive files on the system.

MitigationImplement strict input validation on the filename parameter to reject path traversal sequences and ensure files are only accessed within the intended directory boundaries.

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. Identify Bagisto installation
    Search for Bagisto by checking for composer.json with 'bagisto/bagisto' in the project root, or look for the 'packages/Webkul' directory structure typical of Bagisto installations
    Affected if Bagisto is not present in the environment
  2. Determine installed Bagisto version
    Check the composer.json file in the project root for the 'version' field under 'bagisto/bagisto', or inspect the VERSION file if present in the root directory
    Affected if The installed version matches or falls within an affected range (if known)
  3. Locate ImageCacheController
    Find the ImageCacheController file in the codebase - typically located under packages/Webkul/Category/src/Http/Controllers/ or similar ImageCache related paths, or search for files containing 'ImageCacheController'
    Affected if The controller exists and is accessible in the codebase
  4. Verify vulnerability access point
    Identify the route mapping to ImageCacheController - check routes/web.php or routes/api.php for routes pointing to the ImageCache functionality, noting the URL pattern and any required parameters
    Affected if An unauthenticated route exists that accepts a filename parameter and passes it to the file reading logic
  5. Test for path traversal capability
    Send a crafted HTTP request to the ImageCache endpoint with a path traversal sequence such as '../../../../etc/passwd' or '../../../../.env' as the filename parameter, and check if the response contains file contents outside the cache directory
    Affected if The application returns content from files outside the intended cache directory

The environment is affected if Bagisto is installed, the ImageCacheController is accessible via an unauthenticated route, and the filename parameter accepts path traversal sequences to read arbitrary files.
