  description: Jira before 8.4.0 is susceptible to server-side request forgery. The /plugins/servlet/gadgets/makeRequest resource contains a logic bug in the JiraWhitelist class, which can allow an attacker to access the content of internal network resources and thus modify data, and/or execute unauthorized operations.
  impact: |
    Successful exploitation of this vulnerability can lead to unauthorized access to internal resources, data leakage, and potential remote code execution.
  remediation: |
    Upgrade Jira to version 8.4.0 or later to mitigate the SSRF vulnerability.
