CVE-2026-40113: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in MervinPraison PraisonAI
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.
AI Analysis
Technical Summary
PraisonAI's deploy.py script prior to version 4.5.128 improperly handles input values for environment variables by directly interpolating openai_model, openai_key, and openai_base into a comma-delimited string used in the gcloud run deploy --set-env-vars command. Since gcloud uses commas to separate key-value pairs, any comma included in these values causes gcloud to interpret trailing text as additional environment variable definitions, enabling argument injection (CWE-88). This can lead to arbitrary environment variables being set in the deployed Cloud Run service, potentially compromising confidentiality and integrity. The vulnerability is resolved in version 4.5.128.
Potential Impact
Successful exploitation allows an attacker with at least limited local privileges (AV:L, PR:L) to inject arbitrary environment variables into the Cloud Run deployment, potentially leading to full compromise of confidentiality and integrity of the deployed service. Availability is not impacted. The vulnerability has a high CVSS score of 8.4, indicating significant risk if exploited.
Mitigation Recommendations
This vulnerability is fixed in PraisonAI version 4.5.128. Users should upgrade to version 4.5.128 or later to remediate this issue. No official patch links were provided, but upgrading to the fixed version is the recommended action. Since this is not a cloud service, remediation depends on user action. Patch status is confirmed by the vendor's versioning information.
