"text": "The vulnerability found in python-werkzeug, which lets attackers carry out denial of service attacks by using carefully crafted multipart data, is considered a moderate issue because it could affect system resources and availability. When this vulnerability is exploited, it can cause the CPU to work excessively hard because the parsing mechanism keeps adding data chunks to an internal buffer without checking boundaries properly. This can result in legitimate requests being delayed or denied as worker processes get overloaded, affecting how well the web application performs and responds. While this problem doesn\u2019t directly compromise data integrity or confidentiality, exploiting it can disrupt the availability of the service, which is why it\u2019s seen as a moderate issue.",
