What is CVE-2026-30928?

The Glances open-source monitoring tool contains a significant vulnerability where the /api/4/config endpoint, prior to version 4.5.1, reveals the entire parsed configuration file, glances.conf, without any filtering of sensitive information. This oversight includes critical credentials such as database passwords, API tokens, JWT signing keys, and SSL key passwords, which could be exploited by unauthorized users. Users are strongly advised to upgrade to version 4.5.1 or later to mitigate this risk and protect sensitive data from exposure.

Affected Version(s)

glances < 4.5.1
