What it is

In Spring AI's tool calling support, the per-request tool list is advertised to the model as a boundary but is not fully enforced when a tool call is dispatched. Under certain conditions, a tool that was not made available to the current request could be invoked, potentially leading to privilege escalation.

Affected versions:

Spring AI: 2.0.0

Spring AI: 1.1.0 through 1.1.8

Spring AI: 1.0.0 through 1.0.9
