{"id":"CVE-2026-126070","state":"PUBLISHED","title":"Action View: Possible XSS vulnerability in Action View strip_tags","description":"Action View is a framework for handling view template lookup and rendering and provides view helpers for building HTML. Prior to 8.1.4.1 and 8.0.5.2, strip_tags in Action View returns its sanitized output marked html_safe, but the underlying sanitizer encodes only &, < and >, leaving \" and ' unencoded. Because ERB does not escape a string marked html_safe, untrusted input passed through strip_tags and rendered inside a quoted HTML attribute value could close the attribute and add new attributes, possibly leading to XSS. Applications that render strip_tags output from untrusted input inside an HTML attribute, for example in a title attribute or a <meta content> tag, are affected. Output rendered as element content is not affected. This issue is fixed in versions 8.1.4.1 and 8.0.5.2.","publishedAt":"2026-11-10T20:38:50.694Z","updatedAt":"2026-11-10T20:38:50.694Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["rails rails"],"affected":[{"vendor":"rails","product":"rails","versions":[{"version":"< 8.0.5.2","status":"affected"},{"version":">= 8.1, < 8.1.4.1","status":"affected"}]}],"references":["https://github.com/rails/rails/security/advisories/GHSA-rq8q-p985-fjq7","https://github.com/rails/rails/commit/568b19cb860322885593e308a7f27aceb779e9d7","https://github.com/rails/rails/commit/c3772a10f405f9644125cbb484adfd2aa7a25a59","https://github.com/rails/rails/releases/tag/v8.0.5.2","https://github.com/rails/rails/releases/tag/v8.1.4.1"],"weaknesses":["CWE-79"],"ingestedAt":"2026-11-10T20:52:06.957Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/126xxx/CVE-2026-126070.json","commit":"cd87b009c69cb95c2b9f35c35b81e00a7c52601d","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-126070","state":"PUBLISHED","datePublished":"2026-11-10T20:38:50.694Z","dateUpdated":"2026-11-10T20:38:50.694Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-11-10T17:07:43.284Z"},"containers":{"cna":{"title":"Action View: Possible XSS vulnerability in Action View strip_tags","descriptions":[{"lang":"en","value":"Action View is a framework for handling view template lookup and rendering and provides view helpers for building HTML.
