Published Dec 5, 2024 · corrected/updated Dec 5, 2024 · hoverfly hoverfly · evidence confidence very high

Hoverfly is a lightweight service virtualization/ API simulation / API mocking tool for developers and testers. The POST handler allows users to create new simulation views from the contents of a user-specified file. This feature can be abused by an attacker to read arbitrary files from the Hoverfly server.
