{"id":"CVE-2022-32209","details":"# Possible XSS Vulnerability in Rails::Html::SanitizerThere is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer.This vulnerability has been assigned the CVE identifier CVE-2022-32209.Versions Affected: ALLNot affected: NONEFixed Versions: v1.4.3## ImpactA possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both `select` and `style` elements.Code is only impacted if allowed tags are being overridden. 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`:```\u003c%= sanitize @comment.body, tags: [\"select\", \"style\"] %\u003e```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).","aliases":["GHSA-pg8v-g4xq-hww9"],"modified":"2026-04-10T04:48:06.615451Z","published":"2022-06-24T15:15:11.153Z","related":["SUSE-SU-2022:2870-1","SUSE-SU-2022:2885-1","openSUSE-SU-2024:12145-1","openSUSE-SU-2024:13137-1","openSUSE-SU-2024:14175-1","openSUSE-SU-2025:15125-1","openSUSE-SU-2026:10361-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00045.html"},{"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://lists.debian.org/debian-lts-announce/2022/12/msg00012.html"},{"type":"EVIDENCE","url":"https://hackerone.com/reports/1530898"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rails/rails-html-sanitizer","events":[{"introduced":"0"},{"fixed":"f83f08c81a3a33ce0fb1c379933c416ae80672fa"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.4.3"}]}}],"versions":["v1.0.0","v1.0.1","v1.0.2","v1.0.3","v1.0.4","v1.1.0","v1.2.0","v1.3.0","v1.4.0","v1.4.1","v1.4.2"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"35"}]},{"events":[{"introduced":"0"},{"last_affected":"36"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-32209.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
