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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://go.dev/cl/855121","tags":[]},{"url":"https://go.dev/issue/82622","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/sqrs2vTx_Xs","tags":[]},{"url":"https://pkg.go.dev/vuln/GO-2026-6866","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
