CVE-2026-107839
7.5 HIGHpublic exploit availablePublished 2026-10-09 · Updated 2026-10-14
AI risk analysis
- Summary
- The ageLANServer application has a memory exhaustion vulnerability in its cloud file handling endpoint that allows remote attackers to crash the server by sending oversized JSON requests without any size limits on the request body or array lengths. This can lead to service unavailability and disconnection of active players.
- Exploitability
- Exploitation is straightforward as it requires only sending a specially crafted POST request to the /game/cloud/getFileURL endpoint with an oversized JSON names array, with no authentication required.
- Blast radius
- The vulnerability affects all users running ageLANServer versions prior to 1.15.2, potentially causing widespread service disruption for multiplayer gaming sessions and making the server unavailable until manual restart.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to version 1.15.2 or later to remediate this memory exhaustion vulnerability.

NVD description
ageLANServer provides a cross-platform web server and launcher for offline multiplayer in several Age of Empires and Age of Mythology games. 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.
