This may be done via application configuration:```ruby# In config/application.rbconfig.action_view.sanitized_allowed_tags = [\"select\", \"style\"]```see https://guides.rubyonrails.org/configuring.html#configuring-action-viewOr it may be done with a `:tags` option to the Action View helper `sanitize`:```<%= sanitize @comment.body, tags: [\"select\", \"style\"] %>```see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitizeOr it may be done with Rails::Html::SafeListSanitizer directly:```ruby# class-level optionRails::Html::SafeListSanitizer.allowed_tags = [\"select\", \"style\"]```or```ruby# instance-level optionRails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: [\"select\", \"style\"])```All users overriding the allowed tags by any of the above mechanisms to include both \"select\" and \"style\" should either upgrade or use one of the workarounds immediately.## ReleasesThe FIXED releases are available at the normal locations.## WorkaroundsRemove either `select` or `style` from the overridden allowed tags.## CreditsThis vulnerability was responsibly reported by [windshock](https://hackerone.com/windshock?type=user).","published":"2022-06-24T00:00:00Z","modified":"2026-07-15T01:48:53.843449875Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"RubyGems","name":"rails-html-sanitizer","fixedVersion":"1.4.3"}],"fix":null,"references":[{"type":"WEB","url":"https://hackerone.com/reports/1530898"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/32xxx/CVE-2022-32209.json"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AGRLWBEB3S5AU3D4TTROIS7O6QPHDTRH/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NHDACMCLWE32BZZTSNWQPIFUAD5I6Q47/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-32209"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2022/12/msg00012.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:53.843449875Z"}}
