{"cve":"CVE-2020-15169","nvd":{"published":"2020-09-11T16:15:12.287","modified":"2026-06-17T02:56:11.280","status":"Modified","description":"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.","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://github.com/rails/rails/security/advisories/GHSA-cfjv-5498-mph5","https://lists.debian.org/debian-lts-announce/2020/10/msg00015.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XJ7NUWXAEVRQCROIIBV4C6WXO6IR3KSB/","https://www.debian.org/security/2020/dsa-4766","https://github.com/rails/rails/security/advisories/GHSA-cfjv-5498-mph5"],"products":["action_view_project:action_view","debian:debian_linux","fedoraproject:fedora"],"source":"nvd","synced_at":"2026-10-19T21:09:20.498348299+00:00"},"epss":{"cve":"CVE-2020-15169","score":0.02372,"percentile":0.83846,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cfjv-5498-mph5","url":"https://osv.dev/vulnerability/GHSA-cfjv-5498-mph5","summary":"XSS in Action View","modified":"2026-09-10T03:49:13.488506001Z","packages":[{"ecosystem":"RubyGems","name":"actionview","purl":"pkg:gem/actionview","ranges":["<5.2.4.4"],"fixed":["5.2.4.4"]},{"ecosystem":"RubyGems","name":"actionview","purl":"pkg:gem/actionview","ranges":[">=6.0.0.0 <6.0.3.3"],"fixed":["6.0.3.3"]}]}],"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).
