Detailsinfo

A vulnerability, which was classified as problematic, has been found in Jovancoding Network-AI up to 5.12.1. Affected by this issue is the function AgentRuntime.readFile of the component AgentRuntime Sandbox. The manipulation with an unknown input leads to a sandbox vulnerability. Using CWE to declare the problem leads to CWE-265. Impacted is confidentiality. CVE summarizes:

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, `AgentRuntime` promises scoped file access under a configured sandbox `basePath`, but its path containment checks use raw string prefix tests. A sandbox base such as `/tmp/network-ai-sandbox` also matches a sibling path such as `/tmp/network-ai-sandbox_evil/secret.txt`. An agent/user that can call `AgentRuntime.readFile()` or `AgentRuntime.listDir()` can read or list files outside the intended sandbox when the target path is in a sibling directory sharing the base path prefix. This breaks the documented sandbox boundary. The issue is fixed in v5.12.2. `SandboxPolicy.resolvePath()` and `isPathAllowed()` now use separator-anchored prefix checks (`resolved === base || resolved.startsWith(base + path.sep)`) for both the allow-list and block-list. A sibling directory that merely shares a name prefix (e.g. `/srv/app-evil` vs base `/srv/app`) is no longer treated as in-scope.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-58481 since 06/30/2026. The exploitation is known to be easy. The attack may be launched remotely.
