Prior to version 1.15.2, the AoE3 POST /game/cloud/getFileURL handler in the bundled game server has no request body size limit or cap on the attacker-controlled JSON names array and allocates response storage directly from the unbounded array length. A remote unauthenticated client can use the default self-registration flow and send an oversized request that causes excessive memory allocation, crashes or hangs the server process, disconnects active players, and keeps the service unavailable until it is restarted. This issue is fixed in version 1.15.2.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-400"],"references":["https://github.com/luskaner/ageLANServer/commit/1dd40166a59356865c0a4b1800f32d05dc8bec79","https://github.com/luskaner/ageLANServer/releases/tag/v1.15.2","https://github.com/luskaner/ageLANServer/security/advisories/GHSA-4jfq-pmq9-257h","https://github.com/luskaner/ageLANServer/security/advisories/GHSA-4jfq-pmq9-257h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107839","score":0.00415,"percentile":0.35481,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4jfq-pmq9-257h","url":"https://osv.dev/vulnerability/GHSA-4jfq-pmq9-257h","summary":"ageLANServer: Unbounded JSON Array Allocation in AoE3 Cloud `getFileURL` Endpoint Leads to Remote Denial of Service","modified":"2026-10-19T21:41:15.645419481Z","packages":[{"ecosystem":"Go","name":"github.com/luskaner/ageLANServer/server","purl":"pkg:golang/github.com/luskaner/ageLANServer/server","ranges":["<1.8.2-0.20260809203301-1dd40166a593"],"fixed":["1.8.2-0.20260809203301-1dd40166a593"]}]},{"id":"GO-2026-6716","url":"https://osv.dev/vulnerability/GO-2026-6716","summary":"ageLANServer: Unbounded JSON Array Allocation in AoE3 Cloud `getFileURL` Endpoint Leads to Remote Denial of Service in github.com/luskaner/ageLANServer/server","modified":"2026-10-19T21:31:37.809070286Z","packages":[{"ecosystem":"Go","name":"github.com/luskaner/ageLANServer/server","purl":"pkg:golang/github.com/luskaner/ageLANServer/server","ranges":["<1.8.2-0.20260809203301-1dd40166a593"],"fixed":["1.8.2-0.20260809203301-1dd40166a593"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
