CVE-2026-103905 (GCVE-0-2026-103905)
Vulnerability from cvelistv5
Published

Modified
2026-10-14 14:10
Severity ?
8.7 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE
  • CWE-306 - Missing authentication for critical function
Summary
The authentication middleware of the JTL-Shop administration backend processes the plugin safe mode toggle on the admin logout route before checking whether the requesting user is authenticated. An unauthenticated remote attacker can therefore switch the shop's plugin safe mode on and off, which deactivates all installed plugins and their functionality, such as payment and shipping integrations, resulting in a shop-wide denial of service. The attack requires a single request and can be automated against many installations.

CVE-2026-103904 (GCVE-0-2026-103904)
Vulnerability from cvelistv5
Published
2026-10-14 10:23
Modified
2026-10-14 14:11
Severity ?
8.6 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N
9.3 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N
CWE
  • CWE-79 - Improper neutralization of input during web page generation ('cross-site scripting')
Summary
The public consent endpoint of JTL-Shop accepts arbitrary consent names from unauthenticated visitors without validating them against the configured consent items. These names are stored in the consent statistics and rendered without output encoding in the administration backend. An unauthenticated remote attacker can thereby inject script code that is executed in the browser session of an administrator viewing the consent statistics page, allowing actions to be performed with the administrator's privileges.
