CVE-2026-111612: Use of Hard-coded Cryptographic Key in qaiu netdisk-fast-download
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.

Technical Analysis
The vulnerability in netdisk-fast-download (<=0.4.8) involves the use of a hard-coded AES key ('nfd_auth_key2026') in the ParserApi's /v2/randomAuth endpoint. Attackers can repeatedly invoke this endpoint to obtain encrypted authentication blobs (encryptedAuth) and decrypt them using the known AES key. This leads to disclosure of other users' cloud-drive credentials such as cookies, tokens, or passwords, without requiring any authentication or user interaction.
Potential Impact
An unauthenticated attacker can retrieve and decrypt sensitive authentication credentials of other users, leading to potential unauthorized access to users' cloud-drive accounts. This compromises confidentiality of user credentials and may result in account takeover or data exposure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using affected versions and monitor vendor communications for updates.
