CVE-2024-28194Public exploitNetwork attack vector

Authentication bypass via hardcoded JWT signing secret

Published Mar 13, 2024 · Updated Aug 2, 2024

Authentication bypass in YourSpotify before 1.8.0 allows remote attackers to authenticate as arbitrary users through forged JWT cookies. The /spotify route signs tokens and the baselogged middleware verifies them with the same source-visible MyPrivateKey string in every deployment. Exploitation requires a valid userId, obtainable through the /accounts endpoint, and grants the target user's privileges, including administrator access.
