 ### Fixes
 
+- Security/Commands: enforce sender-only matching for `commands.allowFrom` by blocking conversation-shaped `From` identities (`channel:`, `group:`, `thread:`, `@g.us`) while preserving direct-message fallback when sender fields are missing. Ships in the next npm release. Thanks @jiseoung.
 - Security/Config writes: block reserved prototype keys in account-id normalization and route account config resolution through own-key lookups, hardening `/allowlist` and account-scoped config paths against prototype-chain pollution.
 - Security/Exec: harden `safeBins` long-option validation by rejecting unknown/ambiguous GNU long-option abbreviations and denying sort filesystem-dependent flags (`--random-source`, `--temporary-directory`, `-T`), closing safe-bin denylist bypasses. Thanks @jiseoung.
 - Security/Channels: unify dangerous name-matching policy checks (`dangerouslyAllowNameMatching`) across core and extension channels, share mutable-allowlist detectors between `openclaw doctor` and `openclaw security audit`, and scan all configured accounts (not only the default account) in channel security audit findings.
