Vulnerability description
DayBreach CVE AI Research
CVE-2026-59318 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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
