{"id":"CVE-2026-59162","aliases":["GHSA-fx5j-qcqg-grpf"],"url":"https://o3.security/vulnerability/CVE-2026-59162","summary":"Excelize: Negative shared-string index causes panic in GetCellValue and GetRows","details":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, Excelize parses shared-string cell values with strconv.Atoi and checks only the upper bound before indexing the shared string slice, allowing an XLSX file containing a shared-string cell with -1 to trigger sharedStrings[-1] and panic when read through GetCellValue or GetRows. This issue is fixed in version 2.11.0.","published":"2026-07-10T15:51:26.078Z","modified":"2026-08-12T03:51:17.104076596Z","cvss":null,"epss":{"score":0.00385,"percentile":0.31957,"asOf":"2026-09-11"},"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-2026-59162.json"},{"type":"ADVISORY","url":"https://github.com/qax-os/excelize/security/advisories/GHSA-fx5j-qcqg-grpf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59162"},{"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":"2026-08-12T03:51:17.104076596Z"}}
