## Overview

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

## Affected

- `spring_ai >= 1.0.0, < 1.0.10`
- `spring_ai >= 1.1.0, < 1.1.9`
- `spring_ai >= 2.0.0, < 2.0.1`

## Remediation

Upgrade past the affected range:

- `spring_ai 2.0.1`
