Technical details

The /external_tools/list endpoint in MISP Modules' website sub-application exposes the api_key field of configured external tools via JSON serialization, accessible without authentication. Additionally, the browser-based edit form pre-populates and stores the API key in the DOM and client-side reactive state, increasing exposure in transit and in memory. This allows unauthenticated network clients to retrieve credentials used for server-to-service authentication.
