Title

OpenClaw < 2026.3.22 - Remote File URL Acceptance in Windows Media Loaders

Summary

OpenClaw before 2026.3.22 contains a path traversal vulnerability in Windows media loaders that accepts remote-host file URLs and UNC-style paths before local-path validation. Attackers can exploit this by providing network-hosted file targets that are treated as local content, bypassing intended access restrictions.

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-25 08:57 – Source website

Summary

OpenClaw: Windows-compatible env override keys could bypass system.run approval binding

Details

Summary

Before OpenClaw 2026.4.2, system-run approval binding normalized environment override keys differently from host execution. Windows-compatible keys could be omitted from the approval binding while still being injected at execution time.

Impact

An approved command could run with attacker-chosen environment overrides that were not represented in the approval binding. This created an approval-integrity gap for affected host-exec flows.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.4.1
Patched versions: >= 2026.4.2
Latest published npm version: 2026.4.1

Fix Commit(s)

7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d — align approval binding with execution-time env-key normalization

Release Process Note

The fix is present on main and is staged for OpenClaw 2026.4.2. Publish this advisory after the 2026.4.2 npm release is live.

Thanks @iskindar for reporting, and thanks @wsparks-vc for coordination.

Severity

6.9 (Medium)

Windows-compatible keys could be omitted from the approval binding while still being injected at execution time.\n\n## Impact\n\nAn approved command could run with attacker-chosen environment overrides that were not represented in the approval binding. This created an approval-integrity gap for affected host-exec flows.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c= 2026.4.1`\n- Patched versions: `\u003e= 2026.4.2`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `7eb094a00d80e9f6bf0e62f2c45d3b88ff67c04d` \u2014 align approval binding with execution-time env-key normalization\n\n## Release Process Note\n\nThe fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live.\n\nThanks @iskindar for reporting, and thanks @wsparks-vc for coordination.",
