From 2.8.1 to 2.11.0, ANCHORARRAY recursively calls the exported CalcCellValue function, creating a fresh calculation context at each cycle and bypassing in-flight and iteration controls. ANCHORARRAY calls CalcCellValue instead of cellResolver, so each recursive hop receives a new calcContext and loses cycle state. When mutually referencing dynamic-array formulas are evaluated directly or through formula-evaluating APIs, each recursion hop resets the cycle budget and prevents completion-based caches from breaking the cycle, allowing an attacker to cause a fatal Go stack overflow and abort the process. No fixed version is available as of this review."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"qax-os","product":"excelize","versions":[{"version":">= 2.8.1, <= 2.11.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-07T18:50:55.568606Z","id":"CVE-2026-107216","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-674"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:excelize:excelize:*:*:*:*:*:go:*:*","versionStartIncluding":"2.8.1","versionEndIncluding":"2.11.0","matchCriteriaId":"EC7558E8-0FE7-4960-9946-5E5189D0ADE3"}]}]}],"references":[{"url":"https://github.com/qax-os/excelize/commit/ea12859e43c64d498ecf839263c5f917391f3316","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/qax-os/excelize/security/advisories/GHSA-wp2g-vpjj-g53r","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]}]}
