CVE-2026-2274
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 · uneditedA SSRF and Arbitrary File Read vulnerability in AppSheet Core in Google AppSheet prior to 2025-11-23 allows an authenticated remote attacker to read sensitive local files and access internal network resources via crafted requests to the production cluster. This vulnerability was patched and no customer action is needed.
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 confidenceThis vulnerability in Google AppSheet Core allowed an authenticated remote attacker to exploit Server-Side Request Forgery (SSRF) combined with arbitrary file read capabilities. By sending crafted requests to the production cluster, attackers could access sensitive local files on the server and pivot to internal network 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.
-
Confirm you use Google AppSheet CoreCheck your application deployment documentation or AppSheet admin console to verify that Google AppSheet Core is the platform hosting your applications.Affected if Your environment does not use Google AppSheet Core as the hosting platform.
-
Identify your AppSheet Core versionAccess the AppSheet admin console or check your deployment configuration to retrieve the installed AppSheet Core version number.Affected if You cannot determine the version or are running a version released before the 2025-11-23 patch date.
-
Verify production cluster usageCheck your AppSheet environment settings to confirm whether production cluster endpoints are enabled or accessible.Affected if Production cluster endpoints are exposed and accessible to authenticated users.
-
Review authentication configurationExamine your AppSheet authentication settings to determine if external or unauthenticated access paths exist that could allow attacker authentication.Affected if Authenticated user access to AppSheet Core production clusters is permitted.
You are affected if your environment runs Google AppSheet Core on a production cluster with authenticated access enabled, and your version predates the November 2025 patch.
