Vulnerability from github – Published: 2026-09-12 00:31 – Updated: 2026-10-03 00:31

Details

An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the setup routine that regenerates the value will use the known default, allowing an attacker aware of the default to forge valid authentication cookies for that component.

Severity

5.9 (Medium)
