Description
Predibase LoRAX through 0.12.1 contains a sensitive information exposure vulnerability that writes the caller-supplied api_token from POST /generate request bodies into router logs. Attackers with access to router logs or OTLP trace backends can recover other users' private-adapter tokens recorded through the instrumented GenerateParameters span field.
