{"id":"CVE-2025-53092","state":"PUBLISHED","title":"Strapi core vulnerable to sensitive data exposure via CORS misconfiguration","description":"Strapi is an open source headless content management system. Strapi versions prior to 5.20.0 contain a CORS misconfiguration vulnerability in default installations. By default, Strapi reflects the value of the Origin header back in the Access-Control-Allow-Origin response header without proper validation or whitelisting. This allows an attacker-controlled site to send credentialed requests to the Strapi backend. An attacker can exploit this by hosting a malicious site on a different origin (e.g., different port) and sending requests with credentials to the Strapi API. The vulnerability is fixed in version 5.20.0. No known workarounds exist.","publishedAt":"2025-10-16T16:29:35.246Z","updatedAt":"2025-10-16T18:13:08.618Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["strapi strapi"],"affected":[{"vendor":"strapi","product":"strapi","versions":[{"version":"< 5.20.0","status":"affected"}]}],"references":["https://github.com/strapi/strapi/security/advisories/GHSA-9329-mxxw-qwf8"],"weaknesses":["CWE-200","CWE-284","CWE-364","CWE-942"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/53xxx/CVE-2025-53092.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-53092","state":"PUBLISHED","datePublished":"2025-10-16T16:29:35.246Z","dateUpdated":"2025-10-16T18:13:08.618Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-06-25T13:41:23.085Z"},"containers":{"cna":{"title":"Strapi core vulnerable to sensitive data exposure via CORS misconfiguration","descriptions":[{"lang":"en","value":"Strapi is an open source headless content management system.
