Technical details

A capture-replay vulnerability exists in MPP.Methods.Tempo.KeyAuthorization.verify/3 where signed authorization tokens lack challenge-binding; the same signature verifies against any server challenge with matching subscription terms. MPP.Methods.Tempo.Subscription.activate/4 deduplicates by challenge ID only, so a replayed credential with a fresh challenge bypasses deduplication, allowing repeated subscription transactions and wallet charges bounded only by expiry and chain semantics.

Affected products

ZenHive mpp 0.14.0 to before 0.16.2
