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.","epss":{"date":"2026-11-12","percentile":0.19253,"score":0.00269},"exploits":[],"kev":null,"metrics":[{"score":6.1,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},{"score":6.1,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794506497330,"publishedAt":1794343130694,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/rails/rails/security/advisories/GHSA-rq8q-p985-fjq7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/rails/rails/commit/568b19cb860322885593e308a7f27aceb779e9d7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/rails/rails/commit/c3772a10f405f9644125cbb484adfd2aa7a25a59"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/rails/rails/releases/tag/v8.0.5.2"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/rails/rails/releases/tag/v8.1.4.1"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/rails/rails/commit/568b19cb860322885593e308a7f27aceb779e9d7"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/rails/rails/commit/c3772a10f405f9644125cbb484adfd2aa7a25a59"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/rails/rails/releases/tag/v8.0.5.2"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/rails/rails/releases/tag/v8.1.4.1"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/rails/rails/security/advisories/GHSA-rq8q-p985-fjq7"}],"remediation":[],"revision":"ca19a6665b329f41ee923236ad76adfc8ecc7bae453bc91ee50e24e0e185110b","sources":[{"modifiedAt":1794506497330,"name":"CNA: GitHub_M","retrievedAt":1794506997645,"url":"https://www.cve.org/CVERecord?id=CVE-2026-126070"},{"modifiedAt":1794345565117,"name":"NVD","retrievedAt":1794357163737,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126070"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794507013605,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-126070"}],"ssvc":{"assessedAt":1794500788666,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Action View: Possible XSS vulnerability in Action View strip_tags","updatedAt":1794507013605}
