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."}],"source":{"advisory":"GHSA-9h9g-93gc-623h","discovery":"UNKNOWN"}},"adp":[{"title":"CVE Program Container","references":[{"name":"https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-9h9g-93gc-623h","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-9h9g-93gc-623h"},{"name":"https://hackerone.com/reports/1656627","tags":["x_refsource_MISC","x_transferred"],"url":"https://hackerone.com/reports/1656627"},{"url":"https://lists.debian.org/debian-lts-announce/2023/09/msg00012.html","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00045.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T21:46:00.596Z"}}]}}
