Appsmith versions prior to 1.98 expose sensitive instance management API endpoints without authentication. Unauthenticated attackers can query endpoints like /api/v1/consolidated-api/view and /api/v1/tenants/current to retrieve configuration metadata, license information, and unsalted SHA-256 hashes of admin email domains for reconnaissance and targeted attack planning.

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 1.96, a Critical Stored XSS vulnerability exists in the Table Widget (TableWidgetV2). The root cause is a lack of HTML sanitization in the React component rendering pipeline, allowing malicious attributes to be interpolated into the DOM. By leveraging the "Invite Users" feature, an attacker with a regular user account (user@gmail.com) can force a System Administrator to execute a high-privileged API call (/api/v1/admin/env), resulting in a Full Administrative Account Takeover. This vulnerability is fixed in 1.96.

Appsmith is a platform to build admin panels, internal tools, and dashboards. In versions 1.94 and below, publicly accessible apps allow unauthenticated users to execute unpublished (edit-mode) actions by sending viewMode=false (or omitting it) to POST /api/v1/actions/execute. This bypasses the expected publish boundary where public viewers should only execute published actions, not edit-mode versions. An attack can result in sensitive data exposure, execution of edit‑mode queries and APIs, development data access, and the ability to trigger side effect behavior. This issue does not have a released fix at the time of publication.

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 1.93, the server uses the Origin value from the request headers as the email link baseUrl without validation. If an attacker controls the Origin, password reset / email verification links in emails can be generated pointing to the attacker’s domain, causing authentication tokens to be exposed and potentially leading to account takeover. This vulnerability is fixed in 1.93.

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 1.52. 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.

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.

Appsmith is a platform to build admin panels, internal tools, and dashboards. Users invited as "App Viewer" should not have access to development information of a workspace. Datasources are such a component in a workspace. Yet, in versions of Appsmith prior to 1.51, app viewers are able to get 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. The attacker needs to have been invited to a workspace as a "viewer", by someone in that workspace with access to invite. The attacker then needs to be able to signup/login to that Appsmith instance. The issue is patched in version 1.51. No known workarounds are available.

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.

Server-Side Request Forgery (SSRF) in GitHub repository appsmithorg/appsmith prior to 1.8.2.

An issue in the Elasticsearch plugin of Appsmith v1.7.11 allows attackers to connect disallowed hosts to the AWS/GCP internal metadata endpoint.

Appsmith v1.7.11 was discovered to allow attackers to execute an authenticated Server-Side Request Forgery (SSRF) via redirecting incoming requests to the AWS internal metadata endpoint.

Server-side JavaScript injection in Appsmith through 1.7.14 allows remote attackers to execute arbitrary JavaScript code from the server via the currentItem property of the list widget, e.g., to perform DoS attacks or achieve an information leak.
