AnalysisAIv1 – Sep 15, 2026

The npm package praisonai exposes a SandboxExecutor 'network-isolated' mode that is advertised to users as 'No network access (proxy blocked)' but only injects http_proxy/https_proxy=http://localhost:0 without creating any operating-system network boundary, so sandboxed commands that ignore proxy environment variables can still open sockets directly. Versions 1.2.3 through 1.7.1 of the npm package are affected; an initial fix shipped in 1.7.2. A local-only proof-of-concept is described in the vendor advisory (a plain Node HTTP client reaches a loopback server while a proxy

DescriptionCVE.org

PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, SandboxExecutor network-isolated mode in src/praisonai-ts/src/cli/features/sandbox-executor.ts uses buildEnv() only to inject invalid http_proxy and https_proxy environment variables and does not establish an operating-system network boundary. Programs that ignore those proxy variables can open sockets directly, allowing supposedly isolated commands to reach localhost, internal services, cloud metadata, or external hosts and potentially exfiltrate data. An initial remediation was released in version 1.7.2.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
