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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200","CWE-284","CWE-364","CWE-942"],"references":["https://github.com/strapi/strapi/security/advisories/GHSA-9329-mxxw-qwf8"],"products":["strapi:strapi"],"source":"nvd","synced_at":"2026-10-19T22:12:35.277909958+00:00"},"epss":{"cve":"CVE-2025-53092","score":0.00289,"percentile":0.21209,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9329-mxxw-qwf8","url":"https://osv.dev/vulnerability/GHSA-9329-mxxw-qwf8","summary":"Strapi core vulnerable to sensitive data exposure via CORS misconfiguration","modified":"2026-02-03T03:03:57.813541Z","packages":[{"ecosystem":"npm","name":"@strapi/core","purl":"pkg:npm/%40strapi/core","ranges":["<5.20.0"],"fixed":["5.20.0"]}]}],"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).
