kin-openapi has uncontrolled resource consumption in openapi3filter deepObject query parameter decoding

Summary An uncontrolled resource consumption vulnerability in openapi3filter lets any unauthenticated client force multi-gigabyte heap allocation with a single, tiny HTTP request. When a spec declares a deepObject-style query parameter whose schema contains an array a normal, documented pattern,...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value through sliceMapToSlice in openapi3filter/reqrespdecoder.go. An attacker can force multi-gigabyte heap allocation and a denial of service by sending a deepObject query parameter with a large...
