The attachment download resource in Atlassian Jira Server and Data Center before 8.5.5, and from 8.6.0 before 8.8.2, and from 8.9.0 before 8.9.1 allows remote attackers to inject arbitrary HTML or JavaScript via a Cross-Site Scripting (XSS) vulnerability issue attachments with a mixed multipart content type.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to version 8.5.5, 8.6.0 prior to 8.8.2 or 8.9.0 prior to 8.9.1. It is, therefore, affected by multiple vulnerabilities:

- A flaw which allows remote attackers to inject arbitrary HTML or JavaScript via a Cross-Site Scripting (XSS) vulnerability issue attachments with a vnd.wap.xhtml+xml content type (CVE-2020-4024).

- A flaw which allows remote attackers to inject arbitrary HTML or JavaScript via a Cross-Site Scripting (XSS) vulnerability in Issue attachments (CVE-2020-4022).
