{"id":"CVE-2026-48489","aliases":["GHSA-6h46-9jf5-q59x"],"url":"https://o3.security/vulnerability/CVE-2026-48489","summary":"Symfony: Security Firewall Bypass via failure_forward Subrequest: Unauthenticated Access to access_control-Protected GET Routes","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.53, 6.4.41, 7.4.13, and 8.0.13, DefaultAuthenticationFailureHandler honored the request-supplied _failure_path parameter when failure_forward: true was enabled, allowing an unauthenticated failing login request to dispatch a subrequest to access_control-protected GET routes that skipped firewall listeners. This issue is fixed in versions 5.4.53, 6.4.41, 7.4.13, and 8.0.13.","published":"2026-07-14T19:14:12.233Z","modified":"2026-08-12T03:51:24.783783122Z","cvss":null,"epss":{"score":0.00596,"percentile":0.45832,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/security-http","fixedVersion":"5.4.53"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"5.4.53"},{"ecosystem":"Packagist","name":"symfony/security-http","fixedVersion":"6.4.41"},{"ecosystem":"Packagist","name":"symfony/security-http","fixedVersion":"7.4.13"},{"ecosystem":"Packagist","name":"symfony/security-http","fixedVersion":"8.0.13"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"6.4.41"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"7.4.13"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"8.0.13"}],"fix":{"url":"https://github.com/symfony/symfony/commit/c48a4276309e11aedeeb0ce3a89dfbf0b4fe04ff","label":"symfony/symfony@c48a427"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v5.4.53"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v6.4.41"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v7.4.13"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48489.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-6h46-9jf5-q59x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48489"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/c48a4276309e11aedeeb0ce3a89dfbf0b4fe04ff"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.783783122Z"}}
