monetr is a budgeting application for recurring expenses. Prior to version 1.12.5, a server-side request forgery (SSRF) vulnerability in monetr's Lunch Flow integration allowed any authenticated user on a self-hosted instance to cause the monetr server to issue HTTP GET requests to arbitrary URLs supplied by the caller, with the response body from non-200 upstream responses reflected back in the API error message. This issue has been patched in version 1.12.5.
