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`).","cwe":["CWE-22"],"affected":[{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"1.0.0","version_end":"3.3.22","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"},{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"4.0.0","version_end":"4.0.22","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"},{"package":null,"product":"J2Store extension for Joomla","vendor":"j2commerce.com","ecosystem":null,"cpe":null,"version_start":"4.1.0","version_end":"4.1.7","version_end_inclusive":true,"fixed_version":null,"type":null,"source":"nvd"}],"references":[{"url":"https://www.j2commerce.com/","title":null,"source":"nvd"}],"source_records":[{"source":"nvd","external_id":"CVE-2026-81568","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81568","severity":"HIGH","cvss_score":8.7,"cvss_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","cvss_version":"4.0","first_seen_at":"2026-09-26T09:34:35.497556Z","last_seen_at":"2026-09-26T09:34:35.497556Z"}],"history":[{"at":"2026-09-26T09:34:35.497556Z","event":"created","source":"nvd","detail":"Détectée via nvd"}]}}
