CVE-2024-42056
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRetool (self-hosted enterprise) through 3.40.0 inserts resource authentication credentials into sent data. Credentials for users with "Use" permissions can be discovered (by an authenticated attacker) via the /api/resources endpoint. The earliest affected version is 3.18.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceRetool self-hosted enterprise versions 3.18.1 through 3.40.0 contain an information disclosure vulnerability where resource authentication credentials are inadvertently included in API responses from the /api/resources endpoint. Any authenticated user with 'Use' permissions can query this endpoint to discover plaintext credentials for configured resources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Retool versionCheck the installed version of Retool self-hosted (typically visible in the Retool admin console footer or in deployment metadata)Affected if The installed version is >= 3.18.1 and <= 3.40.0
-
Verify API resources endpoint exposureInspect whether the /api/resources endpoint is accessible in the Retool instanceAffected if The endpoint is reachable and responds to authenticated requests
-
Confirm user has Use permissionsCheck if any authenticated user账户 has 'Use' permissions on configured resources in RetoolAffected if Users exist with 'Use' permissions on resources (this enables the attack vector)
-
Inspect API response for credentialsAs an authenticated user with Use permissions, query the /api/resources endpoint and examine the JSON response for plaintext credentialsAffected if The response contains plaintext authentication credentials for any configured resources
You are affected if your Retool self-hosted version is between 3.18.1 and 3.40.0 inclusive and any authenticated user with 'Use' permissions can retrieve plaintext credentials from the /api/resources endpoint.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Retool self-hosted to a version newer than 3.40.0. Until upgraded, audit access to /api/resources and consider restricting user permissions to limit exposure.
