{"id":"DEBIAN-CVE-2022-23519","details":"rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, a 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 in either of the following ways: allow both \"math\" and \"style\" elements,  or allow both \"svg\" and \"style\" elements. Code is only impacted if allowed tags are being overridden. . This issue is fixed in version 1.4.4. All users overriding the allowed tags to include \"math\" or \"svg\" and \"style\" should either upgrade or use the following workaround immediately: Remove \"style\" from the overridden allowed tags, or remove \"math\" and \"svg\" from the overridden allowed tags.","modified":"2026-09-01T16:05:21.998167598Z","published":"2022-12-14T17:15:11.067Z","upstream":["CVE-2022-23519"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-23519"}],"affected":[{"package":{"name":"ruby-rails-html-sanitizer","ecosystem":"Debian:12","purl":"pkg:deb/debian/ruby-rails-html-sanitizer?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-23519.json"}},{"package":{"name":"ruby-rails-html-sanitizer","ecosystem":"Debian:13","purl":"pkg:deb/debian/ruby-rails-html-sanitizer?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-23519.json"}},{"package":{"name":"ruby-rails-html-sanitizer","ecosystem":"Debian:14","purl":"pkg:deb/debian/ruby-rails-html-sanitizer?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-23519.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
