Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-126070/ (Markdown: https://insights.sbomify.com/CVE-2026-126070/index.md)","id":"CVE-2026-126070","markdown":"https://insights.sbomify.com/CVE-2026-126070/index.md","name":"CVE-2026-126070","record":{"aliases":["DEBIAN-CVE-2026-126070","GHSA-rq8q-p985-fjq7","UBUNTU-CVE-2026-126070"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"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 \u0026, \u003c and \u003e, 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 \u003cmeta content\u003e 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.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Action View: Possible XSS vulnerability in Action View strip_tags","id":"CVE-2026-126070","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":null,"year":"2026"},"n_packages":2,"n_references":5,"next":{"headline":"Active Storage: Possible DoS vulnerability in Active Storage proxy mode via storage errors during streaming","id":"CVE-2026-126071"},"nickname":null,"packages":[{"ecosystem":"RubyGems","fixed":["8.0.5.2"],"introduced":["0"],"last_affected":[],"package":"actionview","purl":null,"source":"GHSA-rq8q-p985-fjq7"},{"ecosystem":"RubyGems","fixed":["8.1.4.1"],"introduced":["8.1.0.beta1"],"last_affected":[],"package":"actionview","purl":null,"source":"GHSA-rq8q-p985-fjq7"}],"prev":{"headline":"Action View: Possible XSS vulnerability in Action View tag helpers","id":"CVE-2026-126069"},"products":["rails"],"published":"2026-11-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-11-12","vendors":["rails"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-126070/"}
