Affected: Homebrew: openclaw-cli

### Summary `commands.allowFrom` is documented as a sender authorization allowlist for commands/directives, but command authorization could include `ctx.From` (conversation identity) as a sender candidate.

When `commands.allowFrom` contained conversation-like identifiers (for example Discord `channel:<id>` or WhatsApp group JIDs), command/directive authorization could be granted to participants in that conversation instead of only the intended sender identity.

### Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.2.22-2` - Patched version: `2026.2.23` (released)

### Details Root cause: `resolveSenderCandidates()` in `src/auto-reply/command-auth.ts` always included `ctx.From` in candidate evaluation used by `commands.allowFrom` authorization checks.

`ctx.From` is sender-like in some direct-message contexts, but conversation-like in channel/group/thread contexts. This mixed principal handling allowed conversation identifiers to satisfy sender-only authorization.

### Impact In affected versions, command/directive authorization could become broader than intended when operators configured `commands.allowFrom` with conversation identifiers, allowing unintended users in that conversation to run command-only/directive-only flows.

### Fix Main branch now treats `commands.allowFrom` as sender-only: - `ctx.From` is no longer included as a general sender candidate. - `ctx.From` is only used as fallback when sender fields are absent and the valu…
