Title

OpenClaw < 2026.3.22 - Settings Reconciliation Bypass via Empty Allowlist

Summary

OpenClaw before 2026.3.22 contains a settings reconciliation vulnerability that allows attackers to bypass intended deny-all revocations by exploiting empty allowlist handling. The vulnerability treats explicit empty allowlists as unset during reconciliation, silently undoing intended access control denials and restoring previously revoked permissions.

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-17 17:24 – Source website

Summary

OpenClaw: Tlon settings empty-allowlist reconciliation bypassed intended revocation

Details

Summary

Tlon settings reconciliation treated explicit empty allowlists as unset, which could silently undo an intended deny-all revocation.

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

Fix Commit(s)

3cbf932413e41d1836cb91aed1541a28a3122f93

Release Status

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

Code-Level Confirmation

extensions/tlon/src/monitor/index.ts now honors explicit empty allowlists as authoritative deny-all configuration.
extensions/tlon/src/monitor/settings-helpers.test.ts ships regression coverage for explicit empty settings allowlists.

Thanks @zpbrent for reporting.

Severity

2.3 (Low)

Summary

OpenClaw: Tlon settings empty-allowlist reconciliation bypassed intended revocation

Details

Summary

Tlon settings reconciliation treated explicit empty allowlists as unset, which could silently undo an intended deny-all revocation.

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

extensions/tlon/src/monitor/index.ts now honors explicit empty allowlists as authoritative deny-all configuration.
extensions/tlon/src/monitor/settings-helpers.test.ts ships regression coverage for explicit empty settings allowlists.

Thanks @zpbrent for reporting.
