Title

OpenClaw < 2026.4.15 - Arbitrary Local File Read via Webchat Audio Embedding

Summary

OpenClaw before 2026.4.15 contains an arbitrary local file read vulnerability in the webchat audio embedding helper that fails to apply local media root containment checks. Attackers can influence agent or tool-produced ReplyPayload.mediaUrl parameters to resolve absolute local paths or file URLs, read audio-like files, and embed them base64-encoded into webchat responses.

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-10-20 08:59 – Source website

Summary

OpenClaw: Webchat audio embedding could read local files without local-root containment

Details

Impact

OpenClaw deployments before 2026.4.15 could embed host-local audio files into webchat responses without applying the local media root containment check used by other media-serving paths.

If an attacker could influence an agent or tool-produced ReplyPayload.mediaUrl, the webchat audio embedding helper could resolve an absolute local path or file: URL, read an audio-like file under the size cap, and base64-encode it into the webchat media response. This crossed the model/tool-output boundary into a host file read. Prompt injection or malicious tool output is a delivery mechanism; the security boundary failure is the missing local-root containment check.

The impact is narrow: the file had to be readable by the gateway process, have an audio-like extension, and fit within the webchat audio size cap. The issue exposed contents into the webchat assistant/media transcript path; it was not a general remote filesystem API.

Affected Packages / Versions

Package: openclaw on npm
Affected versions: <= 2026.4.14
Patched version: 2026.4.15

The latest public release, 2026.4.21, also contains the fix.

Patches

The public fix threads the applicable local media roots into the webchat audio embedding path and calls assertLocalMediaAllowed before local audio content is read. Current main also includes an additional trustedLocalMedia gate so untrusted model/tool payloads cannot opt into local audio embedding.

Fix commit:

6e58f1f9f54bca1fea1268ec0ee4c01a2af03dde

Workarounds

Upgrade to openclaw@2026.4.15 or later. The latest public release, 2026.4.21, is fixed. Before upgrading, avoid exposing webchat sessions to untrusted prompt/tool content that can influence reply media URLs.

Prompt injection or malicious tool output is a delivery mechanism; the security boundary failure is the missing local-root containment check.\n\nThe impact is narrow: the file had to be readable by the gateway process, have an audio-like extension, and fit within the webchat audio size cap. The issue exposed contents into the webchat assistant/media transcript path; it was not a general remote filesystem API.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` on npm\n- Affected versions: `\u003c= 2026.4.14`\n- Patched version: `2026.4.15`\n\nThe latest public release, `2026.4.21`, also contains the fix.\n\n## Patches\n\nThe public fix threads the applicable local media roots into the webchat audio embedding path and calls `assertLocalMediaAllowed` before local audio content is read. Current `main` also includes an additional `trustedLocalMedia` gate so untrusted model/tool payloads cannot opt into local audio embedding.\n\nFix commit:\n\n- `6e58f1f9f54bca1fea1268ec0ee4c01a2af03dde`\n\n## Workarounds\n\nUpgrade to `openclaw@2026.4.15` or later. The latest public release, `2026.4.21`, is fixed. Before upgrading, avoid exposing webchat sessions to untrusted prompt/tool content that can influence reply media URLs.\n\n## Credits\n\nOpenClaw thanks @zsxsoft for reporting.",
