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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
