Machine-written summary

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

Spring AI's spring-ai-anthropic package, versions 1.1.0 up to 1.1.7, used LLM-influenced filenames without sanitization when resolving paths before writing files to disk. An attacker who can influence those filenames can write files outside the intended directory, including restricted locations. Upgrade spring-ai-anthropic to version 1.1.7 or later. The source gives few details on the exact conditions required for exploitation.
