CVE-2026-105772— Arbitrary file read and write in Google ADK TypeScript (@google/adk) FileArtifactService via path traversal in userId and sessionId

Quick assessment

Affected
Google ADK TypeScript (@google/adk)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Google ADK TypeScript 包（@google/adk）在 0.4.0 至 0.6.0 之前的版本中，其 FileArtifactService 组件存在路径遍历漏洞（CWE-22）。当 ADK API 服务器启用了非默认的 FileArtifactService 并向外暴露时，远程未认证攻击者可通过在 userId 或 sessionId 参数中构造包含相对路径或百分号编码的路径遍历序列（例如 ../ 或 ..%2F），读取与工件目录布局匹配的文件，或在代理工具调用 saveArtifact 时，

Vulnerability Title
Arbitrary file read and write in Google ADK TypeScript (@google/adk) FileArtifactService via path traversal in userId and sessionId
Source: CVE Program / CVE List V5
Vulnerability Description
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.
