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

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 50: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 50% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes Glances (PyPI) <= 4.5.2-dev01, fixed in 4.5.2 . Check your lockfile, including transitive dependencies.

## What it is

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.getserverslist(). 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.

## Affected packages

- PyPI `Glances` <= 4.5.2-dev01 → fixed: 4.5.2

## Affected products (CVE record)

- nicolargo glances: < 4.5.2

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.64% probability of exploitation activity in the next 30 days; percentile 50.
