Description

Mockoon provides way to design and run mock APIs. Prior to 9.7.0, Mockoon's admin API in commons-server/src/libs/server/admin-api.ts is mounted on the same Express listener as user-defined mock routes, enabled by default in shipped runtimes, serves Access-Control-Allow-Origin: * with write methods allowed, and has no authentication. Any unauthenticated caller who can reach the mock server port can read MOCKOON_* environment variables, write arbitrary process environment variables through /mockoon-admin/env-vars, rewrite mock route bodies, statuses, and headers through PUT /mockoon-admin/environment, read transaction logs and SSE streams, and purge state. This issue is fixed in version 9.7.0.
