• CVE-2024-47527: 0.53% estimated exploitation activity in the next 30 days; percentile 44.70 (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 Stored Cross-Site Scripting (XSS) vulnerability in the "Device Dependencies" feature allows authenticated users to inject arbitrary JavaScript through the device name ("hostname" parameter). This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions. Details The vulnerability occurs when creating a device within LibreNMS. An attacker can inject arbitrary JavaScript into the hostname parameter. This malicious script is then executed when another user visits the device dependencies page, resulting in an automatic redirect to a website controlled by the attacker. This redirect can be used to steal session cookies or perform other malicious actions. For example, the following payload can be used to exploit the vulnerability: When the device dependencies page is loaded, this payload triggers the JavaScript, causing the user's browser to redirect to the…

# Patch Next advisory brief: CVE-2024-47527

Advisory: LibreNMS has Stored Cross-site Scripting vulnerability in "Device Dependencies" feature
IDs: CVE-2024-47527, GHSA-rwwc-2v8q-gc9v
Record: https://patchnext.com/advisories/cve-2024-47527 (revision 1, source checked 26 Oct 2026, 14:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: librenms/librenms 24.9.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist librenms/librenms: affected < 24.9.0; fixed in 24.9.0

## Suggested inspection (read-only)
- Packagist librenms/librenms: check the installed version with your package manager.

## 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 librenms/librenms.
- 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://github.com/advisories/GHSA-rwwc-2v8q-gc9v (GitHub-reviewed advisory GHSA-rwwc-2v8q-gc9v lists affected ranges: Packagist librenms/librenms >=0 <24.9.0)
