{"id":"CVE-2026-59161","aliases":["GHSA-q5j5-6p94-4gwc"],"url":"https://o3.security/vulnerability/CVE-2026-59161","summary":"Excelize: Streaming GetRows row-bound bypass causes attacker-controlled allocation","details":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, the streaming worksheet reader used by Rows and GetRows does not enforce the TotalRows limit on the row r attribute, allowing a small XLSX file with a row number above 1048576 and no cell coordinate to make GetRows append empty rows up to the attacker-controlled index and consume excessive memory and CPU. This issue is fixed in version 2.11.0.","published":"2026-07-10T15:47:38.604Z","modified":"2026-08-12T03:51:29.236633922Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","fixedVersion":"2.11.0"},{"ecosystem":"Go","name":"github.com/xuri/excelize","fixedVersion":null}],"fix":{"url":"https://github.com/qax-os/excelize/commit/93f0b3caed37f21ef5079e3259c6c21dcfe68453","label":"qax-os/excelize@93f0b3c"},"references":[{"type":"WEB","url":"https://github.com/qax-os/excelize/releases/tag/v2.11.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59161.json"},{"type":"ADVISORY","url":"https://github.com/qax-os/excelize/security/advisories/GHSA-q5j5-6p94-4gwc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59161"},{"type":"FIX","url":"https://github.com/qax-os/excelize/commit/93f0b3caed37f21ef5079e3259c6c21dcfe68453"},{"type":"FIX","url":"https://github.com/qax-os/excelize/pull/2331"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.236633922Z"}}
