An unauthenticated remote attacker can therefore switch the shop's\nplugin safe mode on and off, which deactivates all installed plugins and their\nfunctionality, such as payment and shipping integrations, resulting in a shop-wide\ndenial of service. The attack requires a single request and can be\nautomated against many installations.","state":0,"publishedAt":"2026-10-14T10:34:34.61+00:00","modifiedAt":"2026-10-14T14:10:58.62+00:00","affected":[{"ecosystem":"Vendor product","name":"JTL-Shop","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"JTL-Software GmbH\",\n                    \"product\": \"JTL-Shop\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.3.0\",\n                            \"lessThan\": \"5.6.5\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.7.0\",\n                            \"lessThan\": \"5.7.5\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.8.0\",\n                            \"lessThan\": \"5.8.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://www.jtl-software.com/de/security/shop-maintenance-mode"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103905","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103905","identifiers":["CVE-2026-103905"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
