This High severity org.webjars.npm:underscore Dependency vulnerability was introduced in versions 5.4, 5.12 and 10.3.0 of Jira Service Management Data Center and Server. This org.webjars.npm:underscore Dependency vulnerability, with a CVSS Score of 7.2 and a CVSS Vector of CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H allows arbitrary code injection via the template function, particularly when the variable option is taken from _.templateSettings as it is not sanitized. Atlassian recommends that Jira Service Management Data Center and Server customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions: * Jira Service Management Data Center and Server 5.4, 5.12 and 10.3: Upgrade to a release greater than or equal to 10.3.1 See the release notes (https://confluence.atlassian.com/servicemanagement/jira-service-management-release-notes-780083086.html). You can download the latest version of Jira Service Management Data Center and Server from the download center (https://www.atlassian.com/software/jira/service-management/download-archives). The National Vulnerability Database provides the following description for this vulnerability: The package underscore from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Injection via the template function, particularly when a variable property is passed as an argument as it is not sanitized.   Note: To mitigate CVE-2021-23358, we upgraded our provided dependency consumption of underscore.js from jira to explicitly consume 1.13.7 (jira/api/underscore-1.13, jira-frontend-api:underscore-1.13) in our latest security and bug fix releases, which are noted as fixed releases above. Moving to one of the fixed versions will stop security scanners from detecting this CVE in those releases. We also want to share that Jira Service Management DC does not utilise underscore.js in a way that makes any versions vulnerable to this CVE.  More specifically we don’t utilise the vulnerable template function in any version of JSMDC. Versions not listed as fixed are not vulnerable to this CVE but may receive alerts from scanners.
