{"id":"AZL-99363","summary":"CVE-2026-83611 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 0.8.15 and 0.9.12, and in xmldom version 0.6.0 and earlier, DOMParser.parseFromString() can silently accept an end tag such as \u003c/a\\njunk\u003e, close the element, and discard the trailing content. On 0.9.x, the lib/sax.js end-tag validator inherits the multiline flag from reg(), allowing the first line to satisfy the anchored XML ETag production; older lines have no equivalent residue validation. This parser differential can bypass a parse-before-trust well-formedness gate, although it does not inject the discarded content; onError on 0.9.x and errorHandler on 0.8.x are the relevant reporting interfaces. This issue is fixed in @xmldom/xmldom versions 0.8.15 and 0.9.12; no fixed version is available for xmldom.","modified":"2026-09-06T05:31:44Z","published":"2026-09-01T15:17:39Z","upstream":["CVE-2026-83611"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83611"}],"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-99363.json"}}],"schema_version":"1.9.0"}
