Some kinds of sensitive information include:\nInformation might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected.  These parties include:\nInformation exposures can occur in different ways:\nIt is common practice to describe any loss of confidentiality as an \"information exposure,\" but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read.  CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.","Draft",2,false,[],{"title":87,"metaDescription":88,"keywords":89,"canonicalUrl":90,"structuredData":91},"What is CVE-2021-20019?
