Who should care

Defenders responsible for netdisk-fast-download deployments should assess exposure and verify the vulnerability, as the /v2/randomAuth endpoint allows unauthenticated credential disclosure.

Why it matters

Defenders should prioritize verifying the vulnerability in netdisk-fast-download versions up to 0.4.8 and assessing exposure, as the /v2/randomAuth endpoint allows unauthenticated credential disclosure.

Credential disclosure allows attackers to recover other users' cloud-drive cookies, tokens, or passwords.
Unauthenticated access to the /v2/randomAuth endpoint enables decryption of the encryptedAuth blob using the hard-coded AES key.

Technical summary

The netdisk-fast-download package through version 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. The vulnerability allows unauthenticated access to sensitive information, which can be used to gain unauthorized access to cloud-drive accounts. Defenders should prioritize verifying the vulnerability in netdisk-fast-download versions up to 0.4.8 and assessing exposure, as the /v2/randomAuth

Defensive priority

Recommended defensive actions

Verify the vulnerability in netdisk-fast-download versions up to 0.4.8
Assess exposure of the /v2/randomAuth endpoint
Implement compensating controls to protect against credential disclosure
Review relevant monitoring, detection, and logs for exposed assets that need extra review
Track exceptions, retest remediated assets, and close the item only after evidence is documented.
Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
