{"id":"CVE-2026-63222","aliases":["GHSA-hhmc-q9hp-r662"],"url":"https://o3.security/vulnerability/CVE-2026-63222","summary":"CodeIgniter: Path traversal in UploadedFile::move() when using client-provided filenames","details":"CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, calling UploadedFile::move() without a second argument uses the client-provided filename without sanitization, allowing a remote attacker to use path traversal sequences to write uploaded content outside the intended directory when the application exposes an upload path. This issue is fixed in version 4.7.4.","published":"2026-07-31T04:06:19.448Z","modified":"2026-09-10T03:30:16.947870317Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"codeigniter4/framework","fixedVersion":"4.7.4"}],"fix":{"url":"https://github.com/codeigniter4/CodeIgniter4/commit/20ebcf4694d96d3c97fbc3938e360730e4f54618","label":"codeigniter4/CodeIgniter4@20ebcf4"},"references":[{"type":"WEB","url":"https://github.com/codeigniter4/CodeIgniter4/releases/tag/v4.7.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63222.json"},{"type":"ADVISORY","url":"https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-hhmc-q9hp-r662"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63222"},{"type":"FIX","url":"https://github.com/codeigniter4/CodeIgniter4/commit/20ebcf4694d96d3c97fbc3938e360730e4f54618"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:30:16.947870317Z"}}
