description

StaffDeck 0.5.6 and earlier are affected by an authentication bypass tied to a built-in application secret. An unauthenticated remote attacker may obtain administrator access to the demo tenant and reach credentials stored there when the default secret and seeded demo account are present.

mitigation

Rotate the StaffDeck application secret and remove or disable the seeded demo tenant and administrator account where present. Restrict StaffDeck access to trusted administrators until a vendor-maintained update is available.
