{"id":"GHSA-9329-mxxw-qwf8","summary":"Strapi core vulnerable to sensitive data exposure via CORS misconfiguration","details":"### Summary\n\nA CORS misconfiguration vulnerability exists in default installations of Strapi where attacker-controlled origins are improperly reflected in API responses.\n\n### Technical Details\n\nBy default, Strapi reflects the value of the Origin header back in the Access-Control-Allow-Origin response header without proper validation or whitelisting.\n\nExample:\n`Origin: http://localhost:8888`\n`Access-Control-Allow-Origin: http://localhost:8888`\n`Access-Control-Allow-Credentials: true`\n\nThis allows an attacker-controlled site (on a different port, like 8888) to send credentialed requests to the Strapi backend on 1337.\n\n### Suggested Fix\n\n1. Explicitly whitelist trusted origins\n2. Avoid reflecting dynamic origins","aliases":["CVE-2025-53092"],"modified":"2026-02-03T03:03:57.813541Z","published":"2025-10-16T19:49:01Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2025-10-16T19:49:01Z","nvd_published_at":"2025-10-16T17:15:33Z","cwe_ids":["CWE-200","CWE-284","CWE-364","CWE-942"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/strapi/strapi/security/advisories/GHSA-9329-mxxw-qwf8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-53092"},{"type":"WEB","url":"https://github.com/strapi/strapi/commit/6e535cb756"},{"type":"PACKAGE","url":"https://github.com/strapi/strapi"},{"type":"WEB","url":"https://github.com/strapi/strapi/releases/tag/v5.20.0"}],"affected":[{"package":{"name":"@strapi/core","ecosystem":"npm","purl":"pkg:npm/%40strapi/core"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.20.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/10/GHSA-9329-mxxw-qwf8/GHSA-9329-mxxw-qwf8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
