openclawnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openclaw to 2026.4.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qrp5-gfw2-gxv4 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-qrp5-gfw2-gxv4 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-qrp5-gfw2-gxv4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qrp5-gfw2-gxv4 in your dependencies?
O3 Security finds GHSA-qrp5-gfw2-gxv4 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
