{"id":"CVE-2024-56408","summary":"PhpSpreadsheet allows unauthorized reflected XSS in `Convert-Online.php` file","details":"PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. Versions prior to 3.7.0, 2.3.5, 2.1.6, and 1.29.7 have no sanitization in the `/vendor/phpoffice/phpspreadsheet/samples/Engineering/Convert-Online.php` file, which leads to the possibility of a cross-site scripting attack. Versions 3.7.0, 2.3.5, 2.1.6, and 1.29.7 contain a patch for the issue.","aliases":["GHSA-x88g-h956-m5xg"],"modified":"2026-04-15T04:48:40.205832Z","published":"2025-01-03T16:05:22.944Z","database_specific":{"cwe_ids":["CWE-79"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56408.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56408.json"},{"type":"ADVISORY","url":"https://github.com/PHPOffice/PhpSpreadsheet/security/advisories/GHSA-x88g-h956-m5xg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56408"},{"type":"FIX","url":"https://github.com/PHPOffice/PhpSpreadsheet/commit/700a80346be269af668914172bc6f4521982d0b4"},{"type":"FIX","url":"https://github.com/PHPOffice/PhpSpreadsheet/commit/9b9a55c7154daa7cd4095f618933c240508ba3c1"},{"type":"FIX","url":"https://github.com/PHPOffice/PhpSpreadsheet/commit/a50ebfe118b3ae0ddaea1c48ac19dc38692f4abc"},{"type":"FIX","url":"https://github.com/PHPOffice/PhpSpreadsheet/commit/b8fac55aa5cb7a3d514c7308378bb37bb711b25e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/phpoffice/phpspreadsheet","events":[{"introduced":"0"},{"fixed":"02c8625411dcb96e1f63d58c47460284e15b2e80"},{"introduced":"4a77798f835119754961a97714f135826a323caa"},{"fixed":"04e8b6edc1bba1bbc8e1aef4111903d11e8323c1"},{"introduced":"b0993b7e4d9c860133365d115b176bc6e0f57022"},{"fixed":"d836f2d7308a192441ccd1546545890b378af913"},{"introduced":"87ddd21eb0b6b7ad20a11d314348ef307475f547"},{"fixed":"2fc12fdc58d39297c7b8c72d65b37a1a25d65ab5"},{"fixed":"700a80346be269af668914172bc6f4521982d0b4"},{"fixed":"9b9a55c7154daa7cd4095f618933c240508ba3c1"},{"fixed":"a50ebfe118b3ae0ddaea1c48ac19dc38692f4abc"},{"fixed":"b8fac55aa5cb7a3d514c7308378bb37bb711b25e"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.29.7"},{"introduced":"2.0.0"},{"fixed":"2.1.6"},{"introduced":"2.2.0"},{"fixed":"2.3.5"},{"introduced":"3.3.0"},{"fixed":"3.7.0"}]}}],"versions":["1.0.0","1.0.0-beta2","1.1.0","1.10.0","1.10.1","1.11.0","1.12.0","1.13.0","1.14.0","1.14.1","1.15.0","1.16.0","1.17.0","1.17.1","1.18.0","1.19.0","1.2.0","1.2.1","1.20.0","1.21.0","1.22.0","1.23.0","1.24.0","1.24.1","1.25.0","1.25.1","1.25.2","1.27.0","1.28.0","1.29.0","1.29.1","1.29.2","1.29.4","1.29.5","1.29.6","1.3.0","1.3.1","1.4.0","1.4.1","1.5.0","1.6.0","1.7.0","1.8.0","1.8.1","1.8.2","2.0.0","2.1.0","2.1.1","2.1.3","2.1.4","2.1.5","2.2.0","2.2.1","2.2.2","2.3.0","2.3.2","2.3.3","2.3.4","3.3.0","3.4.0","3.5.0","3.6.0","phpexcel-last-cherry-picked-commit","phpexcel-last-release-1.8.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-56408.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:L/SI:H/SA:L"}]}
