An issue was discovered in Appsmith before 1.51. Users invited as "App Viewer" incorrectly have access to development information of a workspace (specifically, a list of datasources in a workspace they're a member of). This information disclosure does not expose sensitive data in the datasources, such as database passwords and API Keys.
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.
An issue was discovered in Appsmith before 1.52. An incorrectly configured PostgreSQL instance in the Appsmith image leads to remote command execution inside the Appsmith Docker container. The attacker must be able to access Appsmith, login to it, create a datasource, create a query against that datasource, and execute that query.
AppSmith Community 1.8.3 before 1.46 allows SSRF via New DataSource for application/json requests to 169.254.169.254 to retrieve AWS metadata credentials.
