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.","published":"2026-10-14T11:16:59.000Z","lastModified":"2026-10-16T20:04:30.000Z","status":"Deferred","sourceIdentifier":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-306"],"affected":[],"epss":{"score":0.00531,"percentile":0.44676,"date":"2026-10-27","history":[{"date":"2026-10-15","score":0.00531,"percentile":0.43563}]},"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 (0.53%).
