Versions prior to 20.12.3 and 20.13.0 contain a vulnerability that allows script execution in the admin panel which could lead to cross-site scripting against authenticated admin users. The attack requires an admin user with configuration access, so in practicality it is not very likely to be useful given that a user with this level of access is probably already a full admin. Versions 20.12.3 and 20.13.0 contain a patch for the issue.","publishedAt":"2025-02-28T15:26:14.265Z","updatedAt":"2025-08-26T19:32:15.324Z","severity":{"score":2.9,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["OpenMage magento-lts"],"affected":[{"vendor":"OpenMage","product":"magento-lts","versions":[{"version":"< 20.12.3","status":"affected"}]}],"references":["https://github.com/OpenMage/magento-lts/security/advisories/GHSA-5pxh-89cx-4668","https://github.com/OpenMage/magento-lts/commit/d307e5bf75729a2347dde0952fe9fd9fcd9c6aea","https://github.com/OpenMage/magento-lts/releases/tag/v20.12.3","https://github.com/OpenMage/magento-lts/releases/tag/v20.13.0"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:08:47.682Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/27xxx/CVE-2025-27400.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-27400","state":"PUBLISHED","datePublished":"2025-02-28T15:26:14.265Z","dateUpdated":"2025-08-26T19:32:15.324Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-02-24T15:51:17.267Z"},"containers":{"cna":{"title":"Magento vulnerable to stored XSS in theme config fields","descriptions":[{"lang":"en","value":"Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility.
