{"id":"CVE-2020-15169","aliases":["GHSA-cfjv-5498-mph5"],"url":"https://o3.security/vulnerability/CVE-2020-15169","summary":"XSS in Action View","details":"In Action View before versions 5.2.4.4 and 6.0.3.3 there is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped. This is patched in versions 6.0.3.3 and 5.2.4.4. A workaround without upgrading is proposed in the source advisory.","published":"2020-09-11T16:15:12.287Z","modified":"2026-09-09T03:30:49.848016159Z","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":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"actionview","fixedVersion":"5.2.4.4"},{"ecosystem":"RubyGems","name":"actionview","fixedVersion":"6.0.3.3"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XJ7NUWXAEVRQCROIIBV4C6WXO6IR3KSB/"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/10/msg00015.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4766"},{"type":"FIX","url":"https://github.com/rails/rails/security/advisories/GHSA-cfjv-5498-mph5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-09T03:30:49.848016159Z"}}
