BREW-openclaw-cli-CVE-2026-41389 — OpenClaw: Webchat media embedding enforces local-root containment for tool-result files

Affected: Homebrew: openclaw-cli

## Summary

Webchat tool-result media normalization could pass local and UNC-style file paths into the host-side media embedding path without applying the configured local-root containment policy.

## Impact

A crafted tool-result media reference could cause the host to attempt local file reads or Windows UNC/network path access while preparing webchat media blocks. This could disclose allowed host files or trigger network credential exposure on affected Windows deployments. Severity remains medium because exploitation depends on a tool-result media path reaching the webchat embedding path, but the sink is a host-side file read before the user sees the rendered result.

## Affected versions

- Affected: `>= 2026.4.7, < 2026.4.15` - Patched: `2026.4.15`

## Fix

OpenClaw `2026.4.15` hardens the webchat media path and the shared media resolver. Remote-host `file://` URLs and Windows network paths are rejected before filesystem access, and audio embedding now enforces configured `localRoots` containment before `stat` or read operations.

Verified in `v2026.4.15`:

- `src/gateway/server-methods/chat-webchat-media.ts` uses safe file-URL parsing, rejects Windows network paths, and calls `assertLocalMediaAllowed` before probing local audio files. - `src/media/web-media.ts` rejects remote-host `file://` URLs, Windows network paths, and local-root bypasses on the shared media path. - `src/gateway/server-methods/chat-webchat-media.test.ts` covers both remote-host `file://` rejection a…

OpenClaw versions 2026.4.7 before 2026.4.15 fail to enforce local-root containment on tool-result media paths, allowing arbitrary local and UNC file access. Attackers can craft malicious tool-result media references to trigger host-side file reads or Windows network path access, potentially disclosing sensitive files or exposing credentials.
