A security flaw in OpenAI’s ChatGPT application programming interface could be used to initiate a distributed denial-of-service attack on websites, according to a researcher. The discovery was made by Benjamin Flesch, a security researcher in Germany, who detailed the vulnerability and how it could be exploited on GitHub.
According to Flesch, the flaw lies in the API’s handling of HTTP POST requests to the /backend-api/attributions endpoint. The endpoint allows a list of hyperlinks to be provided through the “urls” parameter. The problem arises from an absence of limits on the number of hyperlinks that can be included in a single request, so attackers can easily flood requests with urls via the API.
