Summary

OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation

Details

Summary

Windows local-media handling accepted remote-host file URLs and UNC-style paths before local-path validation, so network-hosted file targets could be treated as local content.

Affected Packages / Versions

Package: openclaw (npm)
Affected: < 2026.3.22
Fixed: >= 2026.3.22
Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87)
Latest published npm version checked: 2026.3.23-2

Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

src/infra/local-file-access.ts now rejects remote-host file: URLs and UNC/network paths as non-local input.
src/media/web-media.ts, src/media-understanding/attachments.normalize.ts, and src/agents/sandbox-paths.ts all route through the shared local-file guard.

OpenClaw thanks @RacerZ-fighting, @Fushuling for reporting.

CVE-2026-34426 (GCVE-0-2026-34426)

Vulnerability from cvelistv5 – Published: 2026-04-02 18:25 – Updated: 2026-04-03 16:17 X_Open Source

Title

OpenClaw - Approval Bypass via Environment Variable Normalization

Summary

OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.
