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."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/stenciljs/core"},{"url":"https://github.com/lichoin/TraceLoom/blob/main/CVEs/CVE-2026-79320.md"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-79","lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')"}]}],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":6.1,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","integrityImpact":"LOW","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"LOW"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-09-24T12:48:26.689808Z","id":"CVE-2026-79320","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T12:49:11.875Z"}}]},"dataVersion":"5.2"}
