{"id":"AZL-99336","summary":"CVE-2026-83619 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. From 0.7.0 until 0.8.15, the release-0.8.x parser in lib/sax.js trims captured end-tag names with the unanchored global expression /[ \\t\\n\\r]+$/g. For an end tag containing a long whitespace run followed by a non-whitespace character, the expression retries from each possible starting position and backtracks quadratically before failing its end anchor. DOMParser.parseFromString() reaches the path under default options, allowing a small unauthenticated XML input to stall the Node.js event loop; the 0.9.x and unscoped npm lines do not contain this expression. This issue is fixed in @xmldom/xmldom version 0.8.15.","modified":"2026-09-07T05:28:29Z","published":"2026-09-01T15:17:40Z","upstream":["CVE-2026-83619"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83619"}],"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-99336.json"}}],"schema_version":"1.9.0"}
