BREW-OPENCLAW-CLI-CVE-20… (GHSA-QRP5-GFW2-GXV4)
Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-25 08:57 – Source websiteAffected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
< 2026.4.20 - Patched version:
2026.4.20
Impact
Bundled MCP and LSP tools could be appended to the agent's effective tool set after the normal tool-policy pipeline had already filtered core tools. If an operator configured a restrictive policy, such as a tool profile, explicit allow/deny list, owner-only tool restriction, sandbox tool policy, or subagent tool policy, a bundled MCP/LSP tool could remain available even though the same policy would have denied it.
The issue required a configured bundled MCP or LSP tool source and an operator policy that should have restricted that tool. This was a local agent policy-enforcement bypass, not an unauthenticated remote gateway compromise. Severity is medium.
Fix
OpenClaw now applies a final effective tool policy pass to bundled MCP/LSP tools before merging them into the tool set used by normal runs and compaction. The pass covers profile policy, provider profile policy, global/agent/group policies, owner-only filtering, sandbox tool policy, and subagent tool policy.
