vendor appsmith appsmith

An issue was discovered in Appsmith before 1.51. A user on Appsmith that doesn't have admin permissions can trigger the restart API on Appsmith, causing a server restart. This is still within the Appsmith container, and the impact is limited to Appsmith's own server only, but there is a denial of service because it can be continually restarted. This is due to incorrect access control checks, which should check for super user permissions on the incoming request. VulnCheck canary evidence.
