These paths stringify their input and treat the result as already-escaped markup, so an attacker who controls such a string during server-side rendering can inject arbitrary HTML and execute script under the application's origin.","state":0,"publishedAt":"2026-09-19T11:53:34.294+00:00","modifiedAt":"2026-09-21T20:47:06.182+00:00","affected":[{"ecosystem":"Vendor product","name":"hono","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"honojs\",\n                    \"product\": \"hono\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/hono\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"4.13.7\"\n                        },\n                        {\n                            \"version\": \"4.13.7\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":2.3,"severity":"LOW"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/honojs/hono/security/advisories/GHSA-hxh3-vqpv-xpqv","https://www.vulncheck.com/advisories/hono-jsx-before-4.13.7-cross-site-scripting-via-unescaped-strings"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93981","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93981","identifiers":["CVE-2026-93981"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
