{"id":"GHSA-9c3x-r3wp-mgxm","summary":"Symfony allows internal address and port enumeration by NoPrivateNetworkHttpClient","details":"### Description\n\nWhen using the `NoPrivateNetworkHttpClient`, some internal information is still leaking during host resolution, which leads to possible IP/port enumeration.\n\n### Resolution\n\nThe `NoPrivateNetworkHttpClient` now filters blocked IPs earlier to prevent such leaks.\n\nThe fisrt patch for this issue is available [here](https://github.com/symfony/symfony/commit/296d4b34a33b1a6ca5475c6040b3203622520f5b) for branch 5.4.\n\nThe second one is available [here](https://github.com/symfony/symfony/commit/b4bf5afdbdcb2fd03da513ee03beeabeb551e5fa) for branch 5.4 also.\n\n### Credits\n\nWe would like to thank Linus Karlsson and Chris Smith for reporting the issue and Nicolas Grekas for providing the fix.","aliases":["CVE-2024-50342"],"modified":"2026-01-12T19:19:39.149331Z","published":"2024-11-06T15:16:09Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2024-11-06T15:16:09Z","nvd_published_at":"2024-11-06T21:15:05Z","cwe_ids":["CWE-200"]},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/security/advisories/GHSA-9c3x-r3wp-mgxm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50342"},{"type":"WEB","url":"https://github.com/symfony/symfony/commit/296d4b34a33b1a6ca5475c6040b3203622520f5b"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/symfony/http-client/CVE-2024-50342.yaml"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/symfony/symfony/CVE-2024-50342.yaml"},{"type":"PACKAGE","url":"https://github.com/symfony/symfony"},{"type":"WEB","url":"https://symfony.com/cve-2024-50342"}],"affected":[{"package":{"name":"symfony/http-client","ecosystem":"Packagist","purl":"pkg:composer/symfony/http-client"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.3.0"},{"fixed":"5.4.47"}]}],"versions":["v4.3.0","v4.3.1","v4.3.10","v4.3.11","v4.3.2","v4.3.3","v4.3.4","v4.3.5","v4.3.6","v4.3.7","v4.3.8","v4.3.9","v4.4.0","v4.4.0-BETA1","v4.4.0-BETA2","v4.4.0-RC1","v4.4.1","v4.4.10","v4.4.11","v4.4.12","v4.4.13","v4.4.14","v4.4.15","v4.4.16","v4.4.17","v4.4.18","v4.4.19","v4.4.2","v4.4.20","v4.4.21","v4.4.22","v4.4.23","v4.4.24","v4.4.25","v4.4.26","v4.4.27","v4.4.3","v4.4.31","v4.4.33","v4.4.34","v4.4.35","v4.4.36","v4.4.37","v4.4.38","v4.4.39","v4.4.4","v4.4.40","v4.4.41","v4.4.42","v4.4.44","v4.4.45","v4.4.46","v4.4.47","v4.4.49","v4.4.5","v4.4.51","v4.4.6","v4.4.7","v4.4.8","v4.4.9","v5.0.0","v5.0.0-BETA1","v5.0.0-BETA2","v5.0.0-RC1","v5.0.1","v5.0.10","v5.0.11","v5.0.2","v5.0.3","v5.0.4","v5.0.5","v5.0.6","v5.0.7","v5.0.8","v5.0.9","v5.1.0","v5.1.0-BETA1","v5.1.0-RC1","v5.1.0-RC2","v5.1.1","v5.1.10","v5.1.11","v5.1.2","v5.1.3","v5.1.4","v5.1.5","v5.1.6","v5.1.7","v5.1.8","v5.1.9","v5.2.0","v5.2.0-BETA1","v5.2.0-BETA2","v5.2.0-BETA3","v5.2.0-RC1","v5.2.0-RC2","v5.2.1","v5.2.10","v5.2.11","v5.2.12","v5.2.2","v5.2.3","v5.2.4","v5.2.6","v5.2.7","v5.2.8","v5.2.9","v5.3.0","v5.3.0-BETA1","v5.3.0-BETA4","v5.3.0-RC1","v5.3.10","v5.3.11","v5.3.13","v5.3.14","v5.3.2","v5.3.3","v5.3.4","v5.3.7","v5.3.8","v5.4.0","v5.4.0-BETA1","v5.4.0-BETA2","v5.4.0-BETA3","v5.4.0-RC1","v5.4.1","v5.4.11","v5.4.12","v5.4.13","v5.4.14","v5.4.15","v5.4.16","v5.4.17","v5.4.19","v5.4.2","v5.4.20","v5.4.21","v5.4.22","v5.4.23","v5.4.24","v5.4.25","v5.4.26","v5.4.29","v5.4.3","v5.4.31","v5.4.34","v5.4.35","v5.4.36","v5.4.37","v5.4.38","v5.4.39","v5.4.40","v5.4.41","v5.4.42","v5.4.43","v5.4.44","v5.4.45","v5.4.46","v5.4.5","v5.4.7","v5.4.8","v5.4.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-9c3x-r3wp-mgxm/GHSA-9c3x-r3wp-mgxm.json"}},{"package":{"name":"symfony/http-client","ecosystem":"Packagist","purl":"pkg:composer/symfony/http-client"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.4.15"}]}],"versions":["v6.0.0","v6.0.1","v6.0.11","v6.0.12","v6.0.13","v6.0.14","v6.0.15","v6.0.16","v6.0.17","v6.0.19","v6.0.2","v6.0.20","v6.0.3","v6.0.5","v6.0.7","v6.0.8","v6.0.9","v6.1.0","v6.1.0-BETA1","v6.1.0-BETA2","v6.1.0-RC1","v6.1.1","v6.1.11","v6.1.12","v6.1.2","v6.1.3","v6.1.4","v6.1.5","v6.1.6","v6.1.7","v6.1.8","v6.1.9","v6.2.0","v6.2.0-BETA1","v6.2.0-BETA2","v6.2.0-BETA3","v6.2.0-RC1","v6.2.10","v6.2.11","v6.2.12","v6.2.13","v6.2.2","v6.2.5","v6.2.6","v6.2.7","v6.2.8","v6.2.9","v6.3.0","v6.3.0-BETA1","v6.3.0-BETA2","v6.3.0-BETA3","v6.3.0-RC1","v6.3.1","v6.3.11","v6.3.12","v6.3.2","v6.3.5","v6.3.6","v6.3.7","v6.3.8","v6.4.0","v6.4.0-BETA1","v6.4.0-BETA2","v6.4.0-BETA3","v6.4.0-RC1","v6.4.0-RC2","v6.4.10","v6.4.11","v6.4.12","v6.4.13","v6.4.14","v6.4.2","v6.4.3","v6.4.4","v6.4.5","v6.4.6","v6.4.7","v6.4.8","v6.4.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-9c3x-r3wp-mgxm/GHSA-9c3x-r3wp-mgxm.json"}},{"package":{"name":"symfony/http-client","ecosystem":"Packagist","purl":"pkg:composer/symfony/http-client"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.1.8"}]}],"versions":["v7.0.0","v7.0.10","v7.0.2","v7.0.3","v7.0.4","v7.0.5","v7.0.6","v7.0.7","v7.0.8","v7.0.9","v7.1.0","v7.1.0-BETA1","v7.1.0-RC1","v7.1.1","v7.1.2","v7.1.3","v7.1.4","v7.1.5","v7.1.6","v7.1.7"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-9c3x-r3wp-mgxm/GHSA-9c3x-r3wp-mgxm.json"}},{"package":{"name":"symfony/symfony","ecosystem":"Packagist","purl":"pkg:composer/symfony/symfony"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.3.0"},{"fixed":"5.4.47"}]}],"versions":["v4.3.0","v4.3.1","v4.3.10","v4.3.11","v4.3.2","v4.3.3","v4.3.4","v4
