How to fix or mitigate EUVD-2026-21156?

Within 24 hours: Identify all systems running PraisonAI versions prior to 4.5.128 and restrict local access to deployment scripts. Within 7 days: Rotate all OpenAI API keys and Google Cloud credentials that may have been exposed through deployment environments; audit Cloud Run service configuration for unauthorized environment variables. Within 30 days: Upgrade PraisonAI to version 4.5.128 or later once vendor patch is released and validated; implement principle-of-least-privilege access controls for deployment tooling.

Vulnerability Assessment

Weakness	CWE CWE-88 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Argument sanitization
Exploitation Conditions	Attacker requires local access with low-privilege user account on the system running PraisonAI versions prior to 4.5.128. The vulnerability is triggered when deploy.py constructs gcloud run deploy commands with unvalidated openai_model, openai_key, or openai_base parameters containing commas, injecting arbitrary environment variables into Cloud Run services.
Impact	CVSS 8.4 reflects high-impact confidentiality and integrity compromise via local, low-privilege authenticated access. Attack surface limited to users with deploy.py execution rights on development/CI systems. Environment variable injection enables credential theft and service manipulation. Priority depends on deployment model-critical for shared infrastructure, lower for isolated environments.
Exploit ScenarioDerived	Authenticated attacker with local system access embeds comma in openai_key value (e.g., 'sk-xxx,INJECTED_VAR=malicious'). deploy.py passes unsanitized string to gcloud run deploy --set-env-vars, causing gcloud parser to treat injected suffix as new environment variable. No public exploit code identified at time of analysis.

AnalysisAIv1 – Apr 09, 2026

Environment variable injection in PraisonAI deploy.py (versions prior to 4.5.128) allows authenticated local attackers to inject arbitrary environment variables into Google Cloud Run services during deployment. The vulnerability stems from improper validation of comma-separated gcloud CLI arguments, enabling attackers to manipulate openai_model, openai_key, or openai_base parameters with embedded commas, causing gcloud to parse injected content as additional KEY=VALUE pairs. This grants high-level access to confidential service configuration and permits unauthorized modifications. No public exploit identified at time of analysis.

RemediationAI

Vendor-released patch: upgrade to PraisonAI version 4.5.128 or later, which implements input validation for comma characters in gcloud deployment parameters. Until patched, restrict access to deploy.py execution to trusted administrators only, and implement pre-deployment validation to reject configuration values containing commas in openai_model, openai_key, or openai_base fields. Review existing Cloud Run service environment variables for unauthorized entries.

Technical ContextAI · show details

Root cause is CWE-88 argument injection during gcloud run deploy command construction. The deploy.py script concatenates user-controlled openai_model, openai_key, and openai_base values into comma-delimited --set-env-vars string without input sanitization. Comma character acts as delimiter boundary, causing gcloud parser to interpret trailing text fragments as legitimate environment variable definitions in the Cloud Run deployment manifest.

HIGH 8.4

DescriptionGitHub Advisory

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.

Executive ViewAI

Why It Matters

PraisonAI versions before 4.5.128 contain an environment variable injection vulnerability in deployment scripts that allows authenticated users with local system access to inject malicious configuration into Google Cloud Run services, potentially exposing API keys and cloud credentials. Organizations using PraisonAI for cloud deployments face immediate risk of credential compromise and unauthorized service reconfiguration if their teams include untrusted or compromised local users.

Business Impact: High

Compensating Controls

Until vendor patch is available: (1) Restrict local system access and deployment script execution to trusted administrators only; (2) Implement environment variable validation and sanitization at the CI/CD pipeline level before gcloud invocation; (3) Use Cloud Run environment variable encryption and access controls to limit exposure; (4) Monitor Cloud Run service deployments and configuration changes for anomalies; (5) Require multi-factor authentication for all cloud credential access and rotation procedures.
