Phoca Cart (com_phocacart) below 6.1.9 - Unauthenticated Order Download IDOR (paid file disclosure)

Phoca Cart before 6.1.9 does not check who is downloading a purchased file. The order download task loads the ordered file by its numeric id and only checks that the download token and order token sent with the request are not empty. It never compares them with the tokens stored for that order. No login is required: an anonymous visitor who sends any non-empty values for both tokens can step through the sequential download ids and fetch the digital products other customers paid for. Only shops that sell downloadable products are exposed, and the per-file download count and day limits still apply. Phoca describes it as an authorisation bypass through a user-controlled key (IDOR) in the order view. Phoca Cart 6.1.9 (1 October 2026) requires the logged-in owner of the order, or both stored tokens matched exactly. The fix has shipped on the 6.x branch only. The current 5.x release (5.2.4), 4.x release (4.0.13) and 3.x release (3.5.8) all have the same unchecked code and no fixed release. Joomla 5 and Joomla 6 sites should install the 6.1.9 package (a Joomla 5 site is offered the 5.x line by the updater, so install pkg_phocacart_v6.1.9.zip by hand). Joomla 3 and Joomla 4 sites have no fix: unpublish downloadable products, or move to Joomla 5 or 6 and Phoca Cart 6.1.9. A CVE has been announced by Phoca but not yet published.
