{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/69872?format=json","vulnerability_id":"VCID-rb39-w8y8-gqck","summary":"protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.8 and 8.2.0, protobufjs could recurse without a depth limit while expanding nested JSON descriptors through Root.fromJSON() and Namespace.addJSON(). A crafted JSON descriptor with deeply nested namespace definitions could cause the JavaScript call stack to be exhausted during descriptor loading.
