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."}], "lastModified": "2025-11-25T18:44:29.403", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:strapi:strapi:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4129AF63-8F53-43D6-8E8E-DB0FB979FF0D", "versionEndExcluding": "5.20.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
