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-2026-107219 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/xuri/excelize/v2 (Go): affected from 2.3.1; fixed in 2.11.1-0.20260906004932-2badfcd5841d\n- github.com/xuri/excelize/v2 (Go): affected from 2.3.1; fixed in 2.11.1-0.20260906004932-2badfcd5841d\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-2026-107219/ (Markdown: https://insights.sbomify.com/CVE-2026-107219/index.md)","id":"CVE-2026-107219","markdown":"https://insights.sbomify.com/CVE-2026-107219/index.md","name":"CVE-2026-107219","record":{"aliases":["GHSA-jrfj-fhj2-jjvm"],"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":"An attacker can cause CPU exhaustion in applications using Excelize by providing a crafted Excel file with an excessive spinCount during decryption.","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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.3.1 to 2.11.0, agile decryption accepts an attacker-controlled spinCount and performs that many password-key derivation iterations before verifier validation. OpenFile reaches agileDecrypt, which passes the unbounded spinCount to convertPasswdToKey before password verification. When a crafted OLE encrypted-workbook header supplies an excessive spinCount and the file is opened, the key-derivation loop performs unbounded attacker-selected work and cannot be cancelled, allowing an attacker to consume a CPU core for an attacker-controlled duration. No fixed version is available as of this review.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Excelize: Unbounded spinCount in agile decryption burns CPU during OpenFile","id":"CVE-2026-107219","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Excelize: Panic in cellInRange on a worksheet with an empty mergeCell ref","id":"CVE-2026-107220"},"packages":[{"ecosystem":"Go","fixed":["2.11.1-0.20260906004932-2badfcd5841d"],"introduced":["2.3.1"],"last_affected":[],"package":"github.com/xuri/excelize/v2","purl":null,"source":"GHSA-jrfj-fhj2-jjvm"},{"ecosystem":"Go","fixed":["2.11.1-0.20260906004932-2badfcd5841d"],"introduced":["2.3.1"],"last_affected":[],"package":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","source":"GHSA-jrfj-fhj2-jjvm"}],"prev":{"headline":"Excelize: RIGHT() on supplementary-plane text slices with a negative index and panics","id":"CVE-2026-107218"},"products":["excelize"],"published":"2026-10-07","related":[{"cvss_score":8.7,"headline":"Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic","id":"CVE-2026-107211","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":8.7,"headline":"Excelize: Nil-pointer dereference in GetSlicers when a worksheet has extLst present but no drawing element","id":"CVE-2026-107213","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":8.7,"headline":"Excelize: Streaming GetRows row-bound bypass causes attacker-controlled allocation","id":"CVE-2026-59161","kev_date_added":null,"published":"2026-07-10"},{"cvss_score":7.5,"headline":"Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days","id":"CVE-2026-107212","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":7.5,"headline":"Excelize Decrypt: unrecoverable panics on malformed OLE/CFB encrypted workbooks","id":"CVE-2026-107214","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":7.5,"headline":"Excelize: extractPart allocates attacker-controlled, unbounded and negative-sized buffers from CFB directory entries: remote panic / OOM DoS","id":"CVE-2026-107215","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":7.5,"headline":"Excelize ANCHORARRAY: mutually-referencing array formulas recurse unboundedly via re-entrant CalcCellValue, causing a fatal stack overflow","id":"CVE-2026-107216","kev_date_added":null,"published":"2026-10-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-07","vendors":["qax-os"]},"summary":"An attacker can cause CPU exhaustion in applications using Excelize by providing a crafted Excel file with an excessive spinCount during decryption.","url":"https://insights.sbomify.com/CVE-2026-107219/"}
