An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107211 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/xuri/excelize/v2 (Go): affected from 2.8.1; fixed in 2.11.1-0.20261003002531-6258dcebc4e2\n- github.com/xuri/excelize/v2 (Go): affected from 2.8.1; fixed in 2.11.1-0.20261003002531-6258dcebc4e2\n- github.com/xuri/excelize/v2 (Go): affected from 2.8.1; fixed in 2.11.1-0.20261003002531-6258dcebc4e2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-107211/ (Markdown: https://insights.sbomify.com/CVE-2026-107211/index.md)","id":"CVE-2026-107211","markdown":"https://insights.sbomify.com/CVE-2026-107211/index.md","name":"CVE-2026-107211","record":{"aliases":["GHSA-mx22-3794-2vpv","GO-2026-6695"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go Excel library","requires_auth":"none","summary":"A crafted Excel file triggers an unchecked index panic in Excelize, crashing the application processing the spreadsheet.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"excelize","vendor":"excelize"}],"cvss":{"score":8.7,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, separately parsed pivot-table field indices are used to index the pivot-cache field-name slice without bounds checks. extractPivotTableFields uses getPivotCacheFieldsName output while processing GetPivotTables and trusts the dataField fld attribute as an index. When a crafted workbook supplies a pivot-field count mismatch or an out-of-range dataField fld value before GetPivotTables is called, the unchecked index causes a Go slice-bounds panic that escapes the library, allowing an attacker to crash the process or request worker.
