{"id":"CVE-2026-93981","summary":"hono/jsx before 4.13.7 Cross-Site Scripting via Unescaped Strings","details":"hono before 4.13.7 fails to HTML-escape plain strings rendered by hono/jsx as a child or fallback of Suspense, as a string child of ErrorBoundary alongside an asynchronous sibling, as the single child of a Context.Provider, or as the root value passed to renderToString() or renderToReadableStream() from hono/jsx/dom/server. 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.","aliases":["GHSA-hxh3-vqpv-xpqv"],"modified":"2026-09-20T11:47:30.311294116Z","published":"2026-09-19T11:53:34.294Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93981.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93981.json"},{"type":"ADVISORY","url":"https://github.com/honojs/hono/security/advisories/GHSA-hxh3-vqpv-xpqv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93981"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/hono-jsx-before-4.13.7-cross-site-scripting-via-unescaped-strings"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/honojs/hono","events":[{"introduced":"0"},{"fixed":"eebdf7be39abf0a872671835ccce0c4f03ea497a"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"4.13.7"}]}}],"versions":["v4.13.6","v4.13.5","v4.13.4","v4.13.1","v4.13.3","v4.13.2","v4.13.0","v4.12.34","v4.12.33","v4.12.32","v4.12.31","v4.12.30","v4.12.29","v4.12.28","v4.12.27","v4.12.26","v4.12.25","v4.12.24","v4.12.23","v4.12.22","v4.12.21","v4.12.20","v4.12.19","v4.12.18","v4.12.17","v4.12.16","v4.12.15","v4.12.14","v4.12.13","v4.12.12","v4.12.11","v4.12.10","v4.12.9","v4.12.8","v4.12.7","v4.12.6","v4.12.5","v4.12.4","v4.12.3","v4.12.2","v4.12.1","v4.12.0","v4.11.10","v4.11.9","v4.11.8","v4.11.7","v4.11.6","v4.11.5","v4.11.4","v4.11.3","v4.11.2","v4.11.1","v4.11.0","v4.10.8","v4.10.7","v4.10.6","v4.10.5","v4.10.4","v4.10.3","v4.10.2","v4.10.1","v4.10.0","v4.9.12","v4.9.11","v4.9.10","v4.9.9","v4.9.8","v4.9.7","v4.9.6","v4.9.5","v4.9.4","v4.9.3","v4.9.2","v4.9.1","v4.9.0","v4.8.12","v4.8.11","v4.8.10","v4.8.9","v4.8.8","v4.8.7","v4.8.6","v4.8.5","v4.8.4","v4.8.3","v4.8.2","v4.8.1","v4.8.0","v4.7.11","v4.7.10","v4.7.9","v4.7.8","v4.7.7","v4.7.6","v4.7.5","v4.7.4","v4.7.3","v4.7.2","v4.7.1","v4.7.0","v4.6.20","v4.6.19","v4.6.18","v4.6.17","v4.6.16","v4.6.15","v4.6.14","v4.6.13","v4.6.12","v4.6.11","v4.6.10","v4.6.9","v4.6.8","v4.6.7","v4.6.6","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.11","v4.5.10","v4.5.9","v4.5.8","v4.5.7","v4.5.6","v4.5.5","v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.5.0","v4.4.13","v4.4.12","v4.4.11","v4.4.10","v4.5.0-rc.2","v4.4.9","v4.4.8","v4.4.7","v4.4.6","v4.5.0-rc.1","v4.4.5","v4.4.4","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.11","v4.3.10","v4.3.9","v4.3.8","v4.3.7","v4.3.6","v4.3.5","v4.3.4","v4.3.3","v4.3.2","v4.3.1","v4.3.0","v4.2.9","v4.2.8","v4.2.7","v4.2.6","v4.2.5","v4.2.4","v4.2.3","v4.2.2","v4.2.1","v4.2.0","v4.1.7","v4.1.6","v4.1.5","v4.1.4","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.10","v4.1.0-rc.1","v4.0.9","v4.0.8","v4.0.7","v4.0.6","v4.0.5","v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0.0","v3.12.12","v3.12.11","v3.12.10","v3.12.9","v4.0.0-rc.3","v3.12.8","v3.12.7","v4.0.0-rc.2","v3.12.6","v4.0.0-rc.1","v3.12.5","v3.12.4","v3.12.3","v3.12.2","v4.0.0-rc.0","v3.12.1","v3.12.0","v3.11.12","v3.11.11","v3.11.10","v3.11.9","v3.11.8","v3.11.7","v3.11.6","v3.11.5","v3.11.4","v3.11.3","v3.11.2","v3.11.1","v3.11.0","v3.10.5","v3.10.4","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.2","v3.9.1","v3.9.0","v3.9.0-rc.1","v3.8.4","v3.8.3","v3.8.2","v3.8.1","v3.8.0","v3.8.0-rc.3","v3.7.6","v3.8.0-rc.2","v3.7.5","v3.8.0-rc.1","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.6.0-rc.2","v3.6.0-rc.1","v3.5.8","v3.5.7","v3.5.6","v3.5.5","v3.5.4","v3.5.3","v3.5.2","v3.5.1","v3.5.0","vv3.5.0-rc.1","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.4","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.3.0-rc.1","v3.2.7","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.2.0-rc.3","v3.2.0-rc.1","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v3.0.0-rc.16","v3.0.0-rc.15","v2.7.8","v3.0.0-rc.14","v3.0.0-rc.13","v2.7.7","v2.7.6","v3.0.0-rc.9","v3.0.0-rc.10","v2.7.5","v2.7.4","v2.7.3","v3.0.0-rc.5","v2.7.2","v3.0.0-rc.4","v2.7.1","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.10","v2.5.9","v2.5.8","v2.5.7","v2.5.6","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.5.1","v2.5.0","v2.4.1","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.9","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.6.5-0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.6.0-0","v1.5.2","v1.5.1","v1.5.0","v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.0","v0.5.10","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0",
