GEN-001: Allowing users to enter incorrect data

Description	If a specification requires some field to be in a specific format, applications should have proper server-side validation to prevent their users from entering incorrect data. Perfect examples are fields where the value is expected to be an email or a URL.
Estimated severity	MAJOR
Examples
Suggested action	Enforce absolute compliance with the specification
How communicated	Monitoring system Problem occurred for at least 15 providers in PROD (link1, link2)

Estimated severity	CRITICAL
Examples
Suggested action	Enforce absolute compliance with the specification
How communicated	Monitoring system Problem occurred for at least 11 providers in PROD

GEN-003: Attaching request body in error-response

Description	A provider attaches full request body and parameters in error-responses in the Stats Portal
Estimated severity	MEDIUM
Examples
Suggested action	A provider should stop doing this, because it might result in leaking private data when such errors are reported to the Stats Portal
How communicated	Monitoring system Problem occurred for at least 2 providers in PROD (link1, link2) and 1 other in DEV

GEN-004: Attaching stack trace in error-response

Description	Full stack traces aren't helpful to other partners and are only making reports in the Stats Portal less readable.
Estimated severity	LOW
Examples
Suggested action	In case of unknown errors it is enough to return some generic message, e.g. "Something went wrong. Administrators have been notified. We'll try to fix it ASAP.", as suggested in the specification.
How communicated	Monitoring system Problem occurred for at least 2 providers in PROD (link1, link2).
