What is CVE-2026-40113?
CVE-2026-40113 is a high-severity command injection vulnerability in MervinPraison PraisonAI, published on 9 Apr 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
PraisonAI is a multi-agent teams system. Prior to 4.5.128, deploy.py constructs a single comma-delimited string for the gcloud run deploy --set-env-vars argument by directly interpolating openai_model, openai_key, and openai_base without validating that these values do not contain commas. gcloud uses a comma as the key-value pair separator for --set-env-vars. A comma in any of the three values causes gcloud to parse the trailing text as additional KEY=VALUE definitions, injecting arbitrary environment variables into the deployed Cloud Run service. This vulnerability is fixed in 4.5.128.
Weakness: CWE-88
