OpenClaw: Cross-account sender authorization expansion in `/allowlist ... --store` account scoping

Summary

### Summary `/allowlist ... --store` resolved the selected channel `accountId` for reads, but store writes still dropped that `accountId` and wrote into the legacy unscoped pairing allowlist store.

Because default-account reads still merge legacy unscoped entries, a store entry intended for one account could silently authorize the same sender on the `default` account.

This is a real cross-account sender-authorization scoping bug. Severity is set to **medium** because exploitation requires an already-authorized user who can run `/allowlist` edits.

### Affected Packages / Versions - Package: `openclaw` (npm) - Latest published version checked: `2026.3.2` - Affected versions: `<= 2026.3.2` - Fixed on `main`: March 7, 2026 in `70da80bcb5574a10925469048d2ebb2abf882e73` - Patched release: `2026.3.7`

### Details The affected path was: - `src/auto-reply/reply/commands-allowlist.ts:386-393` resolved `accountId` and read store state with it - `src/auto-reply/reply/commands-allowlist.ts:697-702` and `src/auto-reply/reply/commands-allowlist.ts:730-733` wrote store state without passing `accountId` - `src/pairing/pairing-store.ts:231-234` and `src/pairing/pairing-store.ts:534-554` still merged legacy unscoped allowlist entries into the `default` account

The fix scopes `/allowlist ... --store` writes to the resolved account and clears legacy default-account store entries on removal so legacy reads no longer create cross-account authorization bleed-through.

### Impact - Vulnerability class: improper authorization scoping / incorrect authorization - Exploitation requires: an already-authorized sender who can run `/allowlist` edits - Security effect: unintended authorization expansion from one channel account into `default`

### Fix Commit(s) - `70da80bcb5574a10925469048d2ebb2abf882e73` — scope `/allowlist ... --store` writes by account and clean up legacy default-account removals

### Release Process Note npm `2026.3.7` was published on March 8, 2026. This advisory is fixed in the released package.
