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
In the module "JA Marketplace" (jamarketplace) up to version 9.0.1 from JA Module for PrestaShop, a guest can upload files with extensions .php. In version 6.X, the method `JmarketplaceproductModuleFrontController::init()` and in version 8.X, the method `JmarketplaceSellerproductModuleFrontController::init()` allow upload of .php files, which will lead to a critical vulnerability.

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

The JA Marketplace PrestaShop module allows unauthenticated guest users to upload arbitrary .php files through vulnerable controller methods (JmarketplaceproductModuleFrontController::init() in v6.X and JmarketplaceSellerproductModuleFrontController::init() in v8.X). This missing file type validation permits remote code execution by uploading malicious PHP scripts.

MitigationUpdate JA Marketplace module to version 9.0.2 or later which contains the patched file upload validation. If immediate update is not possible, disable the affected controller methods or implement web application firewall (WAF) rules to block .php file uploads to the module's upload directory.

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 JA Marketplace module version
    Locate the module's main file (typically ja_marketplace.php) in modules/ja_marketplace/ and open it to find the version number defined in the $version variable, or check via PrestaShop back office in Modules > Module Manager > JA Marketplace
    Affected if Version is 6.X or 8.X (any subversion)
  2. Determine the vulnerable controller in use
    Inspect the modules/ja_marketplace/controllers/front/ directory - if JmarketplaceproductModuleFrontController.php exists, the v6.X vulnerability path is present; if JmarketplaceSellerproductModuleFrontController.php exists, the v8.X vulnerability path is present
    Affected if Either JmarketplaceproductModuleFrontController.php (v6.X) or JmarketplaceSellerproductModuleFrontController.php (v8.X) controller file exists in the controllers/front folder
  3. Check module upload directory accessibility
    Examine the modules/ja_marketplace/uploads/ directory (or similar upload path configured in the module) and verify it is web-accessible and permits file uploads without validation
    Affected if The module's upload directory exists and is writable by the web server user
  4. Inspect upload directory for suspicious PHP files
    List all files in the module's upload directory and check for any .php files with names that do not match expected module behavior (e.g., shell.php, payload.php, or other unrecognized PHP files)
    Affected if Any .php files are present in the upload directory that were not placed there by the module itself

If the JA Marketplace module version is 6.X or 8.X and the corresponding vulnerable controller is present, the environment is vulnerable to unauthenticated arbitrary file upload and potential remote code execution.

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

Update JA Marketplace module to version 9.0.2 or later which contains the patched file upload validation. If immediate update is not possible, disable the affected controller methods or implement web application firewall (WAF) rules to block .php file uploads to the module's upload directory.
