GHSA-qrp5-gfw2-gxv4 OpenClaw: Bundled MCP/LSP tools could bypass configured tool policy

• npm openclaw: < 2026.4.20 → fixed in 2026.4.20

Affected 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.
