NewCVE-2026-59318 (opens in a new tab)How to fix?
Upgrade org.springframework.ai:spring-ai-model to version 2.0.1 or higher.
Overview
org.springframework.ai:spring-ai-model is a Core model interfaces and classes for Spring AI
Affected versions of this package are vulnerable to Incorrect Authorization through the DefaultToolCallingManager in spring-ai-model/src/main/java/org/springframework/ai/model/tool/DefaultToolCallingManager.java. An attacker can execute a tool that was not attached to the current request by having the model name that tool in a tool call. The manager resolves missing tool names through the application-wide ToolCallbackResolver, so it does not fully enforce request-scoped tool lists at dispatch time. In deployments that register sensitive tools as beans, this can let a model-triggered request invoke destructive or higher-privilege operations outside the tools the caller intended to expose.
Notes
- Additional fixes are available for earlier versions under Enterprise Support (see the Spring Security Advisory for additional details)
