CVE-2026-32633: Glances's Browser API Exposes Reusable Downstream Credentials via `/api/4/serverslist`

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.49% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: glances (Debian:14) 4.5.2+dfsg-1; python-Glances (openSUSE:Tumbleweed) 4.5.2-1.1; glances (PyPI) 4.5.2.

Low priority for now. Upgrade to glances (Debian:14) 4.5.2+dfsg-1; python-Glances (openSUSE:Tumbleweed) 4.5.2-1.1; glances (PyPI) 4.5.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, in Central Browser mode, the `/api/4/serverslist` endpoint returns raw server objects from `GlancesServersList.get_servers_list()`. Those objects are mutated in-place during background polling and can contain a `uri` field with embedded HTTP Basic credentials for downstream Glances servers, using the reusable pbkdf2-derived Glances authentication secret. If the front Glances Browser/API instance is started without `--password`, which is supported and common for internal network deployments, `/api/4/serverslist` is completely unauthenticated. Any network user who can reach the Browser API can retrieve reusable credentials for protected downstream Glances servers once they have been polled by the browser instance. Version 4.5.2 fixes the issue.
