Jira Software Data Center
This High severity RCE (Remote Code Execution) vulnerability was introduced in versions 9.17.2, 10.0.0, 10.1.1, 10.2.0, 10.3.0, 10.4.0, 10.5.0, 10.6.0, 10.7.1, 11.0.0, 11.1.0, 11.2.0, and 11.3.0 of Jira Software Data Center.
This RCE (Remote Code Execution) vulnerability, with a CVSS Score of 7 and a CVSS Vector of CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L allows an unauthenticated attacker to execute arbitrary code which has high impact to confidentiality, low impact to integrity, low impact to availability, and requires no user interaction.
Atlassian recommends that Jira Software Data Center customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions:
- Jira Software Data Center 10.3: Upgrade to a release greater than or equal to 10.3.22

The National Vulnerability Database provides the following description for this vulnerability: Axios is a promise based HTTP client for the browser and Node.js. From 0.19.0 to before 0.31.1 and 1.15.2, Axios contains prototype-pollution gadgets in request config processing. If another vulnerability in the same JavaScript process has already polluted Object.prototype.transformResponse, affected Axios versions may treat that inherited value as request configuration or as an option validator. Axios does not itself create the prototype pollution. Exploitability requires a separate prototype-pollution vulnerability or equivalent attacker control over Object.prototype before Axios creates a request. This vulnerability is fixed in 0.31.1 and 1.15.2.
