CVE-2026-46443Public exploitNetwork attack vector

Authenticated credential disclosure via unstripped filtered response

Published Jun 8, 2026 · Updated Jun 8, 2026

Information exposure in Flowise before 3.1.2 allows remote authenticated users to read encrypted credentials via a filtered API request. The credential service directly appends database entities when credentialName is supplied instead of omitting each entity's encryptedData field. Low privileges and a valid bearer API key are required; the response exposes encrypted credential blobs, while plaintext recovery also requires the server encryption key.
