NVD description
netdisk-fast-download through 0.4.8 contains an information disclosure vulnerability that allows unauthenticated attackers to retrieve donated netdisk credentials via the /v2/randomAuth endpoint in ParserApi. Attackers can repeatedly call the endpoint and decrypt the encryptedAuth blob using the hard-coded AES key nfd_auth_key2026 to recover other users' cloud-drive cookies, tokens, or passwords.
