Phoca Cart: Authorisation bypass in order file download (IDOR)
Summary
Phoca Cart, an e-commerce extension for Joomla, does not verify the download and order tokens of its order-file download endpoint. Any remote user, including a guest without an account, can download other customers' digital goods by enumerating sequential IDs and supplying arbitrary non-empty tokens. The flaw is rated CVSS 8.7 with high confidentiality impact and requires no privileges or user interaction.
Affected
- Phoca Cart extension for Joomla, versions 5.0.0 to 6.1.8
- Vendor: phoca.cz
Fixed in
Unknown. No confirmed fixed version was found in the sources. Check the Phoca Cart download page and changelog for a version later than 6.1.8. Phoca lists pkg_phocacart_v6.1.9.zip, but no source links it to this CVE.
Workaround
- Temporarily disable or unpublish digital-download products if the shop can operate without them
- Restrict or block requests to the component's order-file download endpoint at the web server or WAF
- Review web server logs for unusual download requests and downloads by unknown customers
Exploitation
- No known exploitation reported at the time of research
- No public proof of concept found
- CISA SSVC: Exploitation none, automatable yes, technical impact partial
- Third-party trackers only; re-check CISA KEV
Our recommendation
- Identify all Joomla sites running Phoca Cart and verify the exact version
- On sites running 5.0.0 to 6.1.8, disable digital downloads or restrict the download endpoint until a fix is confirmed
- Check the Phoca changelog and NVD for a confirmed fixed version and update promptly
- Review logs for unusual download activity and assess whether customer files may have been exposed
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
Joomla Extension - phoca.cz - Authorisation bypass through user-controlled key (IDOR) in Order View in Phoca Cart 5.0.0 - 6.1.8 - Phoca Cart's order-file download endpoint does not verify the download tokens it asks for. The d (download token) and o (order token) parameters are checked for non-emptiness only — they are never compared to the stored download_token / order_token values. As a result, any remote user (including a guest with no account at all) can download any customer's digital goods by enumerating sequential id values and supplying arbitrary non-empty tokens.
