Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring AI's spring-ai-client-chat is vulnerable in versions below 1.0.7 and from 1.1.0-M1 up to 1.1.6. A malicious user who can supply input can have it stored in conversation memory, where the model may later interpret it in an unintended way and change its behavior across turns. Upgrade to 1.0.7 or 1.1.6, depending on your release line. The source gives few details about the specific attack conditions.
