{"id":"UBUNTU-CVE-2026-41650","details":"fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks. Prior to version 5.7.0, XMLBuilder does not escape the \"--\u003e\" sequence in comment content or the \"]]\u003e\" sequence in CDATA sections when building XML from JavaScript objects. This allows XML injection when user-controlled data flows into comments or CDATA elements, leading to XSS, SOAP injection, or data manipulation. This issue has been patched in version 5.7.0.","modified":"2026-05-20T16:12:58.867223136Z","published":"2026-05-07T15:16:00Z","upstream":["CVE-2026-41650"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-41650"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-41650"},{"type":"REPORT","url":"https://github.com/NaturalIntelligence/fast-xml-parser/security/advisories/GHSA-gh4j-gqv2-49f6"},{"type":"REPORT","url":"https://github.com/NaturalIntelligence/fast-xml-parser/releases/tag/v5.6.0"}],"affected":[{"package":{"name":"node-webfont","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-webfont?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.4.0+dfsg2+~cs35.7.26-7ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"11.4.0+dfsg2+~cs35.7.26-7ubuntu1","binary_name":"node-webfont"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41650.json"}},{"package":{"name":"node-webfont","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-webfont?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.4.0+dfsg2+~cs35.7.26-10","11.4.0+dfsg2+~cs35.7.26-13ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_version":"11.4.0+dfsg2+~cs35.7.26-13ubuntu2","binary_name":"node-webfont"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41650.json"}},{"package":{"name":"node-webfont","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-webfont?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["11.4.0+dfsg2+~cs35.7.26-13ubuntu2","11.4.0+dfsg2+~cs35.7.26-14","11.4.0+dfsg2+~cs35.7.26-15","11.4.0+dfsg2+~cs35.7.26-16build1","11.4.0+dfsg2+~cs35.7.26-18"],"ecosystem_specific":{"binaries":[{"binary_version":"11.4.0+dfsg2+~cs35.7.26-18","binary_name":"node-webfont"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-41650.json"}}],"schema_version":"1.7.5","severity":[{"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"}]}
