+.Code execution issue
+[%collapsible]
+====
+*Details* +
+In {kib} 7.10.2 to 7.14.0, users with Fleet admin privileges could insecurely upload malicious packages. Due to an older version of the js-yaml library, attackers were able to execute commands on the {kib} server. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22150[CVE-2021-22150]
+*Solution* +
+Upgrade to {kib} 7.14.1.

+.Path traversal issue
+[%collapsible]
+====
+*Details* +
+In {kib} 7.13.4 and earlier, {kib} was not validating the user supplied paths that upload .pbf files, allowing malicious users to arbitrarily traverse the {kib} host to load internal files that end in the .pbf extension. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22151[CVE-2021-22151]
+Thanks to Luat Nguyen of CyberJutsu for reporting this issue.

+[[html-injection-issue]]
+.HTML injection issue
+[%collapsible]
+====
+*Details* +
+In {kib} 7.14.0, {kib} was not sanitizing document fields that contain HTML snippets, allowing attackers with the ability to write documents to an {es} index to inject HTML. When *Discover* highlighted a search term that contained the HTML, the term was rendered. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-37936[CVE-2021-37936]
+*Solution* +
+In <<advanced-options,*Advanced Settings*>>, set `doc_table:highlight` to `false`. If you do not want to change the *Advanced Settings*, upgrade to {kib} 7.14.1.

+In {kib} 7.14.0 and earlier, Node.js 14.17.3 is affected by the following security vulnerabilities: 
+* https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22930[CVE-2021-22930]
+* https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3672[CVE-2021-3672]

+* https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22939[CVE-2021-22939]
+We do not believe an attacker can exploit the security vulnerabilities against {kib}, but are upgrading Node.js out of an abudance of caution. To resolve the security vulnerabilities, {kib} 7.14.1 upgrades Node.js to 14.17.5.
+*Solution* +
+Upgrade to {kib} 7.14.1.
