services / Azure / Web Apps Functions keys

Access keys for an individual Azure Functions function, used as bearer credentials to authorize HTTP invocation of that function.

Function invocation keys are credentials; invoking a function runs code under the function app's (possibly managed) identity. Asset is a single function app -> HIGH.

Microsoft.​Web/​Sites/​functions/​keys/​delete

Deleting a function key revokes the credential legitimate callers use to invoke the function, denying authorized access and disrupting that function's HTTP endpoint.

Risks

1. Denial-of-service (HIGH)
2. Denial-of-access (EVASION)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
