What an attacker can do

A remote unauthenticated attacker can read files matching the artifact directory layout or write files (when an agent tool invokes saveArtifact) outside the intended artifact storage root via crafted relative or percent-encoded path traversal sequences (such as ../ or ..%2F) in the userId or sessionId parameters when the ADK API server is exposed with the non-default FileArtifactService enabled. Vendor/CNA’s CVSS 4.0 assessment (base score 9.1/10) rates confidentiality and integrity impact as high; availability impact as none.
