Prior to 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0, Ods::processTableRow in src/PhpSpreadsheet/Reader/Ods.php accepts an unbounded table:number-rows-repeated attribute from an ODS table row. When the row contains a value, the reader materializes a cell for every repetition without checking the spreadsheet row limit, so a small attacker-controlled ODS file can consume substantial CPU and memory and terminate the PHP worker. Column repetition is separately bounded and is not part of this vulnerability. This issue is fixed in versions 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0.","state":0,"publishedAt":"2026-10-22T17:32:49.724+00:00","modifiedAt":"2026-10-29T11:51:32.42+00:00","affected":[{"ecosystem":"Vendor product","name":"PhpSpreadsheet","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"PHPOffice\",\n                    \"product\": \"PhpSpreadsheet\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.30.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.1.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.2.0, < 2.4.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.3.0, < 3.10.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 4.0.0, < 5.10.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/PHPOffice/PhpSpreadsheet/security/advisories/GHSA-j2w7-387v-m2rq","https://github.com/PHPOffice/PhpSpreadsheet/commit/299993894dce37aa3b64aa23e9a3f4bb77ab0e66","https://github.com/PHPOffice/PhpSpreadsheet/commit/2de29384aa11223ee08136c0e6a9e9981bc1a2eb","https://github.com/PHPOffice/PhpSpreadsheet/commit/980b5c294493856f1a25754f1e8a1d2185b93738","https://github.com/PHPOffice/PhpSpreadsheet/commit/9a0b48622ebfe93fa48cb9bc09ce57303bb07af9","https://github.com/PHPOffice/PhpSpreadsheet/commit/da13f40e8760d599b0e8a296017d4b028b20e86c","https://github.com/PHPOffice/PhpSpreadsheet/releases/tag/1.30.7","https://github.com/PHPOffice/PhpSpreadsheet/releases/tag/2.1.19","https://github.com/PHPOffice/PhpSpreadsheet/releases/tag/2.4.8","https://github.com/PHPOffice/PhpSpreadsheet/releases/tag/3.10.8","https://github.com/PHPOffice/PhpSpreadsheet/releases/tag/5.10.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108359","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108359","identifiers":["CVE-2026-108359"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
