CVE-2026-40113Public exploit

Cloud Run environment-variable injection via unescaped commas

Published Apr 9, 2026 · Updated Apr 9, 2026

Argument injection in PraisonAI before 4.5.128 allows local users to inject environment variables into a deployed Cloud Run service. deploy.py interpolates openai_model, openai_key, and openai_base into one comma-delimited gcloud --set-env-vars value without rejecting commas. Control of one input before deployment is required; an added KEY=VALUE pair can override credentials, redirect outbound LLM traffic, or enable sensitive logging.
