    ## Summary Feishu Raw card Send Surface Can Mint Legacy Card Callbacks That Bypass DM Pairing ## Affected Packages / Versions - Package: `openclaw` - Affected versions: `<= 2026.3.24` - First patched version: `2026.3.25` - Latest published npm version at verification time: `2026.3.24` ## Details Feishu raw card sends could previously mint legacy callback payloads that bypassed DM pairing and let unpaired recipients reach callback handling. Commit `81c45976db532324b5a0918a70decc19520dc354` rejects legacy raw-card command payloads so callbacks stay on the normal paired path. Verified vulnerable on tag `v2026.3.24` and fixed on `main` by commit `81c45976db532324b5a0918a70decc19520dc354`. ## Fix Commit(s) - `81c45976db532324b5a0918a70decc19520dc354`
