      This is a vulnerability in a non-Atlassian dependency. Atlassian's application of this dependency presents a lower, non-critical assessed risk.

      This Critical severity HTTP Request Smuggling vulnerability was introduced in versions 5.16.0, 5.17.0, 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 Service Management Data Center.

      This HTTP Request Smuggling vulnerability, with a CVSS Score of 9.1 and a CVSS Vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H allows an unauthenticated attacker to expose assets in your environment susceptible to exploitation which has no impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.

      The National Vulnerability Database provides the following description for this vulnerability: Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, HttpClientCodec pairs each inbound response with an outbound request by queue.poll() once per response, including for 1xx. If the client pipelines GET then HEAD and the server sends 103, then 200 with GET body, then 200 for HEAD, the queue pairs HEAD with the first 200. The HEAD rule then skips reading that message's body, so the GET entity bytes stay on the stream and the following 200 is parsed from the wrong offset. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
