Vulnerability from cvelistv5 – Published: 2026-10-20 17:50 – Updated: 2026-10-20 18:08

Title

Arbitrary file read and write in Google ADK TypeScript (@google/adk) FileArtifactService via path traversal in userId and sessionId

Summary

Path Traversal (CWE-22) in FileArtifactService in Google ADK TypeScript (@google/adk) versions 0.4.0 before 0.6.0 allows a remote unauthenticated attacker to 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. Applications using the default InMemoryArtifactService are unaffected. Upgrade to @google/adk version 0.6.0 or later.

Severity

9.1 (Critical)

Applications using the default InMemoryArtifactService are unaffected. Upgrade to @google/adk version 0.6.0 or later.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
