When a malicious uploaded file containing an embedded JavaScript payload is viewed by an administrator, the attacker can access and exfiltrate the administrator's authentication token.\r\n\r\nThe compromised token enables unauthorized access to the Shopware Administration API. If the affected administrator account possesses extension‑management privileges, an attacker can upload, install, and activate malicious plugins to achieve arbitrary PHP code execution on the underlying OS with the privileges of the Shopware process.","published":"2026-10-13T19:17:56.000Z","lastModified":"2026-10-20T17:17:28.000Z","status":"Deferred","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},"cwe":["CWE-79"],"affected":[],"epss":{"score":0.00593,"percentile":0.48083,"date":"2026-10-26","history":[{"date":"2026-10-14","score":0.00276,"percentile":0.18659}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.59%).
