Cross-Tenant Attack

Definitions

1. An attack where one tenant in a shared environment gains unauthorized influence, visibility, or access into another tenant's resources. Cross-tenant issues are serious because shared infrastructure depends heavily on strong isolation guarantees.

   In plain English: An attack that breaks isolation between separate customers sharing the same environment.

   Example: "The vulnerability raised alarm because it created a plausible cross-tenant attack path in the shared analytics platform."
