Detailsinfo

A vulnerability, which was classified as critical, has been found in MervinPraison PraisonAI up to 1.7.1. Affected by this issue is the function buildEnv of the file src/praisonai-ts/src/cli/features/sandbox-executor.ts of the component SandboxExecutor. The manipulation with an unknown input leads to a sandbox vulnerability. Using CWE to declare the problem leads to CWE-265. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-57135 since 06/24/2026. The exploitation is known to be easy. The attack may be launched remotely.
