{"id":"GHSA-wjfc-pgfp-pv9c","summary":"Improper Input Validation in nyholm/psr7","details":"### Impact\n\nImproper header parsing. An attacker could sneak in a newline (`\\n`) into both the header names and values. While the specification states that `\\r\\n\\r\\n` is used to terminate the header list, many servers in the wild will also accept `\\n\\n`.\n\n### Patches\n\nThe issue is patched in 1.6.1.\n\n### Workarounds\n\nThere are no known workarounds.\n\n### References\n\n* https://www.rfc-editor.org/rfc/rfc7230#section-3.2.4","modified":"2024-11-29T05:28:02.962505Z","published":"2023-04-21T20:27:30Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2023-04-21T20:27:30Z","nvd_published_at":null,"cwe_ids":["CWE-436"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/Nyholm/psr7/security/advisories/GHSA-wjfc-pgfp-pv9c"},{"type":"WEB","url":"https://github.com/guzzle/psr7/security/advisories/GHSA-q7rv-6hp3-vh96"},{"type":"WEB","url":"https://github.com/guzzle/psr7/security/advisories/GHSA-wxmh-65f7-jcvw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29197"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/nyholm/psr7/2023-04-17.yaml"},{"type":"PACKAGE","url":"https://github.com/Nyholm/psr7"}],"affected":[{"package":{"name":"nyholm/psr7","ecosystem":"Packagist","purl":"pkg:composer/nyholm/psr7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.1"}]}],"versions":["0.1.0","0.2.0","0.2.1","0.2.2","0.2.3","0.3.0","1.0.0","1.0.1","1.1.0","1.2.0","1.2.1","1.3.0","1.3.1","1.3.2","1.4.0","1.4.1","1.5.0","1.5.1","1.6.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/04/GHSA-wjfc-pgfp-pv9c/GHSA-wjfc-pgfp-pv9c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
