{"id":"AZL-99342","summary":"CVE-2026-83607 affecting package python-tensorboard 2.16.2-6","details":"xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. Prior to @xmldom/xmldom versions 0.8.14 and 0.9.11, and in xmldom version 0.6.0 and earlier, Document.createElement(tagName) stores an unvalidated element name and XMLSerializer.serializeToString() emits that name verbatim. The requireWellFormed: true path did not validate the element qualified name or synthesized xmlns:PREFIX declaration, so attacker-controlled tag names could inject attributes, elements, or processing instructions into serialized XML or HTML and could cause cross-site scripting when browser-consumed. The unchecked values violate the XML QName constraint, and default serialization and creation-time createElement() behavior remain permissive. This issue is fixed in @xmldom/xmldom versions 0.8.14 and 0.9.11; no fixed version is available for xmldom.","modified":"2026-09-06T05:31:44Z","published":"2026-09-01T15:17:38Z","upstream":["CVE-2026-83607"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83607"}],"affected":[{"package":{"name":"python-tensorboard","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-tensorboard"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.16.2-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99342.json"}}],"schema_version":"1.9.0"}
