PILOS before 4.8.0 includes a Cross-Origin Resource Sharing (CORS) misconfiguration in its middleware: it reflects the Origin request header back in the Access-Control-Allow-Origin response header without proper validation or a whitelist, while Access-Control-Allow-Credentials is set to true. This behavior could allow a malicious website on a different origin to send requests (including credentials) to the PILOS API. This may enable exfiltration or actions using the victim\u2019s credentials if the server accepts those cross-origin requests as authenticated. Laravel\u2019s session handling applies additional origin checks such that cross-origin requests are not authenticated by default. Because of these session-origin protections, and in the absence of any other unknown vulnerabilities that would bypass Laravel\u2019s origin/session checks, this reflected-Origin CORS misconfiguration is not believed to be exploitable in typical PILOS deployments. This vulnerability has been patched in PILOS in v4.8.0"}], "lastModified": "2025-11-04T18:35:45.133", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:thm:pilos:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "91445D94-4D77-4EFF-A078-6AEF72F6E116", "versionEndExcluding": "4.8.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
