Crowcpp maintains the Crow C++ web framework, a lightweight HTTP server library embedded across application-server and microservice implementations. The vendor's vulnerability profile concentrates on a narrow product scope but skews strongly toward critical-severity outcomes, driven by recurring input-handling and output-encoding weaknesses including path traversal, HTTP request/response splitting, cross-site scripting, and injection flaws that are endemic to web-facing request handlers. Defenders should treat patches for this framework as priority updates where Crow is deployed; live severity and exploitation counts are shown alongside this summary.
