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.","state":0,"publishedAt":"2026-10-07T19:17:34.287+00:00","modifiedAt":"2026-10-13T14:23:15.89+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/qax-os/excelize/commit/2badfcd5841d0d88b0ffea119f5a2f3c53b4910b","https://github.com/qax-os/excelize/pull/2389","https://github.com/qax-os/excelize/security/advisories/GHSA-jrfj-fhj2-jjvm"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107219","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-400"],"productCriteria":["cpe:2.3:a:excelize:excelize:*:*:*:*:*:go:*:*"],"sourceDates":{"published":"2026-10-07T19:17:34.287","lastModified":"2026-10-13T14:23:15.890"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
