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.","state":0,"publishedAt":"2026-10-07T17:51:31.98+00:00","modifiedAt":"2026-10-07T18:51:04.748+00:00","affected":[{"ecosystem":"Vendor product","name":"excelize","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"qax-os\",\n                    \"product\": \"excelize\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.8.1, <= 2.11.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-wp2g-vpjj-g53r","https://github.com/qax-os/excelize/commit/ea12859e43c64d498ecf839263c5f917391f3316"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107216","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107216","identifiers":["CVE-2026-107216"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
