Prior to 4.12.18, the JSX renderer escapes style attribute object values for HTML but not for CSS. Untrusted input in a style object value or property name can therefore inject additional CSS declarations into the rendered style attribute. The impact is limited to CSS and does not allow JavaScript execution or HTML attribute breakout. This vulnerability is fixed in 4.12.18.","state":0,"publishedAt":"2026-05-13T16:16:57.837+00:00","modifiedAt":"2026-10-26T14:10:00.13+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/honojs/hono/security/advisories/GHSA-qp7p-654g-cw7p"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44458","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-74","CWE-116"],"productCriteria":["cpe:2.3:a:hono:hono:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-13T16:16:57.837","lastModified":"2026-10-26T14:10:00.130"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
