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).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://hackerone.com/reports/1530898","https://lists.debian.org/debian-lts-announce/2022/12/msg00012.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AGRLWBEB3S5AU3D4TTROIS7O6QPHDTRH/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NHDACMCLWE32BZZTSNWQPIFUAD5I6Q47/","https://hackerone.com/reports/1530898"],"products":["debian:debian_linux","fedoraproject:fedora","rubyonrails:rails_html_sanitizers"],"source":"nvd","synced_at":"2026-10-19T21:32:39.174919249+00:00"},"epss":{"cve":"CVE-2022-32209","score":0.30229,"percentile":0.98221,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pg8v-g4xq-hww9","url":"https://osv.dev/vulnerability/GHSA-pg8v-g4xq-hww9","summary":"Rails::Html::Sanitizer vulnerable to Cross-site Scripting","modified":"2025-11-04T17:02:22.780977Z","packages":[{"ecosystem":"RubyGems","name":"rails-html-sanitizer","purl":"pkg:gem/rails-html-sanitizer","ranges":["<1.4.3"],"fixed":["1.4.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
