When a downstream application enables the experimental slot fixes option and uses scoped components, assigning a string to the textContent property of such a component's host element causes the value to be parsed as HTML instead of being inserted as text. If an application writes attacker-controlled data to these host elements, the data can be interpreted as markup and script can execute in the context of the application's origin.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://github.com/lichoin/TraceLoom/blob/main/CVEs/CVE-2026-79320.md","tags":[]},{"url":"https://github.com/stenciljs/core","tags":[]}],"exploitRefs":[{"url":"https://github.com/lichoin/TraceLoom/blob/main/CVEs/CVE-2026-79320.md","tags":[]},{"url":"https://github.com/stenciljs/core","tags":[]}],"hasPoc":true,"ai":null}
