OpenClaw: LINE group allowlist scope mismatch with DM pairing-store entries

Summary

In specific LINE configurations, sender IDs approved through DM pairing could also satisfy group allowlist checks when operators expected group sender access to be scoped only to explicit group allowlists.

Affected Packages / Versions

• Package: openclaw (npm)
• Latest published version at triage/update time: 2026.2.25
• Affected: <= 2026.2.25
• Patched: >= 2026.2.26 (planned next release)

Impact

This is a group-authorization scope mismatch. DM pairing-store entries could influence group sender authorization in allowlist mode.

Technical Details

Root cause: group allowlist composition inherited pairing-store entries intended for DM approvals. Under default DM pairing policy, a DM-paired sender could match group allowlist checks.

Fixes on main:

• isolate group allowlist composition from pairing-store entries
• centralize shared DM/group allowlist composition to preserve DM-only pairing behavior
• add regression coverage for LINE and Mattermost policy paths

Fix Commit(s)

• 8bdda7a651c21e98faccdbbd73081e79cffe8be0
• 892a9c24b0f6118729ab5b5f5499b1a7e792dd15 (follow-up refactor hardening)

Release Process Note

patched_versions is pre-set to >= 2026.2.26 so once npm 2026.2.26 is published, this advisory can be published directly without additional version-field edits.

Thanks @tdjackey for reporting.
