handler() checked request["config"].get("malshare_apikey") to decide whether
to report the friendly "Missing MalShare API key" error, but indexing
request["config"] directly raises a KeyError when the request has no
"config" key at all (e.g. the module is invoked before any configuration is
set). Instead of returning the intended misperrors message, the module
crashes with an unhandled exception.
Use request.get("config") or {} so a missing config dict falls back to an
empty one and the existing API-key check reports the expected error instead
of raising.
Verified with flake8 (clean) and the full pytest suite against a local
misp-modules server on port 6775: 161 passed, 4 skipped, 5 subtests passed,
matching the baseline.

request["config"]raises aKeyErrorwhenever the incoming request has no"config"key at all, instead of returning the module's intended friendly error message"Missing MalShare API key".Impact: An analyst who invokes the
malshare_uploadexpansion module without any configuration (e.g. no MalShare API key set up in MISP module settings, soconfigis entirely absent from the request) gets an unhandledKeyErrortraceback surfaced back through MISP instead of a clear "Missing MalShare API key" error explaining what to fix.Fix: Changed the lookup to
(request.get("config") or {}).get("malshare_apikey"), which falls back to an empty dict when"config"is missing, so the friendly error message is returned as intended.Verification
