However, that integration point may itself be a descendant of an element that was foster-parented into a foreign namespace (such as <mglyph> or <malignmark> fostered under <mtext>), causing a parser to resolve the subtree in a different foreign namespace upon re-parsing the rendered output. Continue walking the full ancestor chain and verify that every transition from a non-empty namespace occurs at an HTML integration point before emitting literal text.","epss":{"date":"2026-11-04","percentile":0.10195,"score":0.00202},"exploits":[],"kev":null,"metrics":[{"score":6.1,"severity":"medium","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},{"score":6.1,"severity":"medium","source":"NVD: 134c704f-9b21-4f2e-91b3-4a467353bcc0","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793812658330,"publishedAt":1793137136700,"references":[{"source":"CNA: Go","tags":[],"url":"https://go.dev/cl/855121"},{"source":"CNA: Go","tags":[],"url":"https://go.dev/issue/82622"},{"source":"CNA: Go","tags":[],"url":"https://groups.google.com/g/golang-announce/c/sqrs2vTx_Xs"},{"source":"CNA: Go","tags":[],"url":"https://pkg.go.dev/vuln/GO-2026-6866"},{"source":"security@golang.org","tags":[],"url":"https://go.dev/cl/855121"},{"source":"security@golang.org","tags":[],"url":"https://go.dev/issue/82622"},{"source":"security@golang.org","tags":[],"url":"https://groups.google.com/g/golang-announce/c/sqrs2vTx_Xs"},{"source":"security@golang.org","tags":[],"url":"https://pkg.go.dev/vuln/GO-2026-6866"}],"remediation":[],"revision":"3bf07b92ed9c3ae800d08e87bdc91be2967664b00fb1a0de6afcd64212906bc2","sources":[{"modifiedAt":1793810368817,"name":"CNA: Go","retrievedAt":1793812220619,"url":"https://www.cve.org/CVERecord?id=CVE-2026-97045"},{"modifiedAt":1793812658330,"name":"NVD","retrievedAt":1793816566048,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97045"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793812221045,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97045"}],"ssvc":{"assessedAt":1793810343854,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Check all ancestor namespace transitions when rendering raw text in html in golang.org/x/net","updatedAt":1793816566048}
