{"id":"UBUNTU-CVE-2022-23647","details":"Prism is a syntax highlighting library. Starting with version 1.14.0 and prior to version 1.27.0, Prism's command line plugin can be used by attackers to achieve a cross-site scripting attack. The command line plugin did not properly escape its output, leading to the input text being inserted into the DOM as HTML code. Server-side usage of Prism is not impacted. Websites that do not use the Command Line plugin are also not impacted. This bug has been fixed in v1.27.0. As a workaround, do not use the command line plugin on untrusted inputs, or sanitize all code blocks (remove all HTML code text) from all code blocks that use the command line plugin.","modified":"2025-10-24T04:53:29Z","published":"2022-02-18T15:15:00Z","upstream":["CVE-2022-23647"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-23647"},{"type":"REPORT","url":"https://github.com/PrismJS/prism/security/advisories/GHSA-3949-f494-cm99"},{"type":"REPORT","url":"https://github.com/PrismJS/prism/issues/3340"},{"type":"REPORT","url":"https://github.com/PrismJS/prism/pull/3341"},{"type":"REPORT","url":"https://github.com/PrismJS/prism/commit/e002e78c343154e1c0ddf9d6a0bb85689e1a5c7c"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-23647"}],"affected":[{"package":{"name":"node-prismjs","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-prismjs@1.11.0+dfsg-3?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.0+dfsg-2","1.11.0+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"node-prismjs","binary_version":"1.11.0+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-23647.json"}},{"package":{"name":"node-prismjs","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-prismjs@1.27.0+dfsg+~1.26.0-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23.0+dfsg-1","1.25.0+dfsg-1","1.27.0+dfsg+~1.26.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-prismjs","binary_version":"1.27.0+dfsg+~1.26.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-23647.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:L"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
