Short explanation
In Google Agent Development Kit (ADK) for Python, FileArtifactService builds file paths without the app_name, allowing different applications that share the same root directory and user_id/session_id to list, read, overwrite, or delete each other's artifacts.
The exploit compromises data confidentiality and integrity across applications, leading to unauthorized access and potential data loss.
What should be done?
- Upgrade affected installations to version 1.39.1 or 2.7.0 and later
- Apply the patches released by Google for ADK for Python
- Review FileArtifactService configuration to ensure proper per‑app isolation
Chain of evidence and sources
FileArtifactService, app_name'i dosya yolu oluştururken kullanmadığı için aynı kök dizini ve aynı user_id/ session_id paylaşan uygulamalar birbirlerinin artefaktlarına erişebilir.
Etkilenen sürümler 1.19.0‑1.39.1 öncesi ve 2.0.0a1‑2.7.0 öncesidir; 1.39.1 ve 2.7.0 sürümleri sorunu düzeltir.
Yama mevcut; Google ADK for Python için 8 doğrulanmış yama veya düzeltme sürümü bulunmuştur.
Show the technical text from the sources
Exposure of Resource to Wrong Sphere (CWE-668) in FileArtifactService in Google Agent Development Kit (ADK) for Python (google-adk) versions 1.19.0 before 1.39.1 and 2.0.0a1 before 2.7.0 allows a caller in one application to list, read, overwrite, or delete artifacts belonging to another application when both applications share a FileArtifactService root directory and use the same user_id (and session_id for session-scoped artifacts). FileArtifactService accepted app_name across its public API methods but omitted app_name when constructing on-disk paths (root/users/{user_id}/... instead of root/apps/{app_name}/users/{user_id}/...). Version 2.6.0 scoped writes by app_name but retained a legacy root/users/{user_id} fallback for reads and deletes; version 2.7.0 and the 1.x backport in version 1.39.1 removed the fallback and enforce full per-app path scoping.
