services / Azure / Web Apps Functions host function keys

Host-level function keys for a function app, bearer credentials valid across all functions in the app to authorize HTTP invocation.

Host-wide invocation credentials; invoking functions runs code under the app's (possibly managed) identity.

Microsoft.​Web/​sites/​host/​functionkeys/​delete

Deleting a host-level function key revokes a credential used to invoke functions across the app, denying authorized callers and disrupting the app's HTTP endpoints.

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.
