CVE-2026-100585: OpenClaw permission prompt approval bypass through MCP channel bridge

Source: NVD(opens in a new tab)
Identifier: CVE-2026-100585
Published: September 25, 2026
Record updated: October 9, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.2%

Summary

OpenClaw (npm package `openclaw`) before 2026.7.1 does not enforce the owner-only authorization requirement for Claude Code permission prompts delivered through the MCP channel bridge. An authorized non-owner channel sender with channel command access can approve or deny a pending permission request meant for the owner, so the requested action can proceed without owner consent. The practical impact depends on the pending action and the host capabilities requested by the Claude Code run.

Mitigation

Fixed in version 2026.7.1.
