{"id":"CVE-2026-103905","state":"PUBLISHED","title":"Unauthenticated Plugin Safe Mode Toggle Vulnerability in JTL-Shop","description":"The authentication middleware of the JTL-Shop\nadministration backend processes the plugin safe mode toggle on the admin\nlogout route before checking whether the requesting user is\nauthenticated. 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.","publishedAt":"2026-10-14T10:34:34.610Z","updatedAt":"2026-10-14T14:10:58.620Z","severity":{"score":8.7,"label":"High","version":"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","source":"ENISA"},"assigner":"ENISA","products":["JTL-Software GmbH JTL-Shop"],"affected":[{"vendor":"JTL-Software GmbH","product":"JTL-Shop","defaultStatus":"unaffected","versions":[{"version":"5.3.0","status":"affected","lessThan":"5.6.5","versionType":"semver"},{"version":"5.7.0","status":"affected","lessThan":"5.7.5","versionType":"semver"},{"version":"5.8.0","status":"affected","lessThan":"5.8.2","versionType":"semver"}]}],"references":["https://www.jtl-software.com/de/security/shop-maintenance-mode"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/103xxx/CVE-2026-103905.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-103905","state":"PUBLISHED","datePublished":"2026-10-14T10:34:34.610Z","dateUpdated":"2026-10-14T14:10:58.620Z","assignerShortName":"ENISA","assignerOrgId":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","dateReserved":"2026-10-01T14:12:50.876Z"},"containers":{"cna":{"title":"Unauthenticated Plugin Safe Mode Toggle Vulnerability in JTL-Shop","descriptions":[{"lang":"en","value":"The authentication middleware of the JTL-Shop\nadministration backend processes the plugin safe mode toggle on the admin\nlogout route before checking whether the requesting user is\nauthenticated.
