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-2026-107213 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/xuri/excelize/v2 (Go): affected from 2.9.0; fixed in 2.11.1-0.20260929015830-8ffeb07ec9a3\n- github.com/xuri/excelize/v2 (Go): affected from 2.9.0; fixed in 2.11.1-0.20260929015830-8ffeb07ec9a3\n- github.com/xuri/excelize/v2 (Go): affected from 2.9.0; fixed in 2.11.1-0.20260929015830-8ffeb07ec9a3\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-2026-107213/ (Markdown: https://insights.sbomify.com/CVE-2026-107213/index.md)","id":"CVE-2026-107213","markdown":"https://insights.sbomify.com/CVE-2026-107213/index.md","name":"CVE-2026-107213","record":{"aliases":["GHSA-r7x5-4969-99p7","GO-2026-6687"],"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 causes a nil-pointer dereference in the Excelize library, crashing the application and causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-476","name":"NULL Pointer Dereference"}],"description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets.

When a crafted worksheet contains an extLst element without a drawing element and the application calls GetSlicers, the nil ws.Drawing pointer is dereferenced while resolving the drawing relationship, allowing an attacker to panic and terminate an unprotected process.
