• CVE-2026-35587: 0.40% estimated exploitation activity in the next 30 days; percentile 33.92 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary A Server-Side Request Forgery (SSRF) vulnerability exists in the Glances IP plugin due to improper validation of the publicapi configuration parameter. The value of publicapi is used directly in outbound HTTP requests without any scheme restriction or hostname/IP validation. An attacker who can modify the Glances configuration can force the application to send requests to arbitrary internal or external endpoints. Additionally, when publicusername and publicpassword are set, Glances automatically includes these credentials in the Authorization: Basic header, resulting in credential leakage to attacker-controlled servers. This vulnerability can be exploited to: Access internal network services (e.g., 127.0.0.1, 192.168.x.x) Retrieve sensitive data from cloud metadata endpoints (e.g., 169.254.169.254) Exfiltrate credentials via outbound HTTP requests The issue arises because publicapi is passed directly to the HTTP client (urlopenauth) without validation, allowing unrestricted…

# Patch Next advisory brief: CVE-2026-35587

Advisory: Glances has SSRF in IP Plugin via public_api leading to credential leakage
IDs: CVE-2026-35587, GHSA-g5pq-48mj-jvw8
Record: https://patchnext.com/advisories/cve-2026-35587 (revision 3, source checked 26 Oct 2026, 13:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: glances 4.5.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI glances: affected < 4.5.4; fixed in 4.5.4

## Suggested inspection (read-only)
- `python -m pip show glances`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on glances.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-g5pq-48mj-jvw8 (OSV record GHSA-g5pq-48mj-jvw8 lists affected ranges: PyPI glances >=0 <4.5.4 (fixed))
