Network-reachable adk web with no auth or interaction yields unauth RCE (PR:N/UI:N, C/I/A:H); the pytest-installed prerequisite is a deployment requirement I reflect as AT:P in 4.0 rather than raising 3.1 AC.

A Code Injection vulnerability in adk web in Google Cloud Agent Development Kit (ADK) for Python versions 2.0.0 through 2.6.0 on Python (OSS), Cloud Run, and GKE environments where pytest is installed allows an unauthenticated remote attacker to execute arbitrary code using a crafted test session replay.

AnalysisAI
Remote code execution in Google Cloud Agent Development Kit (ADK) for Python versions 2.0.0 through 2.6.0 allows an unauthenticated remote attacker to run arbitrary code on the host by submitting a crafted test session replay to the 'adk web' developer interface when the pytest package is present. The flaw stems from an incomplete input-restriction check (CWE-184) that lets malicious replay content reach code execution. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target runs the 'adk web' interface from Google ADK for Python 2.0.0-2.6.0 AND that the pytest package is installed in that environment - the description explicitly ties the code-execution path to a crafted test session replay in a pytest-enabled deployment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to a genuinely serious issue: the vendor-supplied CVSS 4.0 vector is AV:N/AC:L/PR:N/UI:N with high vulnerable-system and subsequent-system impact (score 10.0), describing unauthenticated network-reachable RCE. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to google/adk-python v2.7.0 or later (fix commit a16f6da3314b8dcd9925884cd6fc7fc9ffdd570d; release https://github.com/google/adk-python/releases/tag/v2.7.0). … Detailed patch versions, workarounds, and compensating controls in full report. |
