Authenticated file read and internal access via SSRF
Published Feb 19, 2026 · Updated Feb 19, 2026
SSRF in Google AppSheet Core before 2025-11-23 allows remote authenticated users to read local files and access internal services. Google states only that crafted requests to the production cluster trigger the server-side access; the affected request handler and validation failure are undisclosed. A valid AppSheet account is required, and exposure is limited to server-readable files and resources reachable from the production cluster.
