{"id":"CVE-2022-23647","state":"PUBLISHED","title":"Cross-site Scripting in Prism","description":"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.","publishedAt":"2022-02-18T14:50:10.000Z","updatedAt":"2025-04-23T19:02:44.473Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["PrismJS prism"],"affected":[{"vendor":"PrismJS","product":"prism","versions":[{"version":">= 1.14.0, < 1.27.0","status":"affected"}]}],"references":["https://github.com/PrismJS/prism/security/advisories/GHSA-3949-f494-cm99","https://github.com/PrismJS/prism/pull/3341","https://github.com/PrismJS/prism/commit/e002e78c343154e1c0ddf9d6a0bb85689e1a5c7c"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T19:49:40.939Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/23xxx/CVE-2022-23647.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-23647","state":"PUBLISHED","datePublished":"2022-02-18T14:50:10.000Z","dateUpdated":"2025-04-23T19:02:44.473Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-01-19T00:00:00.000Z"},"containers":{"cna":{"title":"Cross-site Scripting in Prism","descriptions":[{"lang":"en","value":"Prism is a syntax highlighting library.
