CVE-2026-81568 Details
Description
Joomla Extension - j2commerce.com - Arbitrary file read via `task=download` in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - `J2StoreModelOrderdownloads::getFilePath()` built the on-disk path to a purchased digital download by concatenating the configured attachment folder with the product file's stored `product_file_save_name`, using only `JPath::clean()` (which normalises separators but does not resolve or reject `..` segments) and a plain `JFile::exists()` check — never confirming the resolved path stayed inside the configured attachment folder. If a product file's `product_file_save_name` ever contained a `../` traversal segment — most plausibly via the CSRF-forgeable admin product-file save actions described in Issue 1, but equally by any future integration or bug that writes that field — any customer holding a valid download `token`/`pid` pair for that product file could have the traversal resolve to a path outside the attachment folder and download any file readable by the web server (e.g. `configuration.php`).
An arbitrary file read vulnerability has been identified in the Joomla extension J2Store, specifically in versions 1.0.0 through 3.3.2, 4.0.0 through 4.0.22, and 4.1.0 through 4.1.7. The issue arises in the 'J2StoreModelOrderdownloads::getFilePath()' method, which constructs the file path for digital downloads by combining the attachment folder with the product file's saved name. This process uses 'JPath::clean()' to normalize file separators but fails to properly validate the path, allowing for directory traversal. If a product file's name included a '../' segment, it could be exploited to access files outside the intended directory, such as 'configuration.php', by customers with a valid download token and product ID.
