CVE-2026-107692: The War Thunder game client transmits its authentication bearer token (auth_jwt) in the very first data packet
CVE-2026-107692 is a medium-severity flaw (CVSS 4.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The War Thunder game client transmits its authentication bearer token (auth_jwt) in the very first data packet after the TCP handshake, using only LZ4 compression rather than encryption. An attacker positioned on the network path can passively intercept and decompress this packet to reveal the plaintext JSON payload. This vulnerability allows for temporary authenticated impersonation, enabling an attacker to access game services and certain user
