CVE-2026-40113

# PoC Concept: Injecting a new environment variable via openai_key # Assume the attacker controls the configuration input. malicious_key = "sk-1234567890abcdef,HACKED_VAR=inject_success" # Inside deploy.py (vulnerable code logic simulation): # command = f"gcloud run deploy ... --set-env-vars=openai_key={malicious_key}" # Resulting command executed: # gcloud run deploy ... --set-env-vars=openai_key=sk-1234567890abcdef,HACKED_VAR=inject_success # Outcome in Cloud Run: # 1. openai_key is set to "sk-1234567890abcdef" # 2. HACKED_VAR is set to "inject_success" (Arbitrary Injection)

Prior to 4.5.128, deploy.py constructs a single comma-delimited string for the gcloud run\ndeploy --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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N", "baseScore": 8.4, "baseSeverity": "HIGH", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.0, "impactScore": 5.8}, {"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N", "baseScore": 8.1, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 5.2}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-88"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:praison:praisonai:*:*:*:*:*:*:*:*", "versionEndExcluding": "4.5.128", "matchCriteriaId": "56CDE5F5-B03C-4C3A-9A92-F61C9DFDA9B1"}]}]}], "references": [{"url": "https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-fvxx-ggmx-3cjg", "source": "[email protected]", "tags": ["Exploit", "Vendor Advisory"]}]}}
