GHSA-9m82-f3wx-p625 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in librenms/librenms. 2 public exploit references exist, so weaponization risk is real. A fix is available for librenms/librenms — see the affected versions and patch details below.
LibreNMS XSS Vulnerability
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-9m82-f3wx-p625 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

Description
Persistent Cross-Site Scripting (XSS) issues in LibreNMS before 1.44 allow remote attackers to inject arbitrary web script or HTML via the dashboard_name parameter in the /ajax_form.php resource, related to html/includes/forms/add-dashboard.inc.php, html/includes/forms/delete-dashboard.inc.php, and html/includes/forms/edit-dashboard.inc.php.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for librenms/librenms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update librenms/librenms to 1.44 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9m82-f3wx-p625 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-9m82-f3wx-p625 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-9m82-f3wx-p625. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-9m82-f3wx-p625 in your dependencies?
O3 Security finds GHSA-9m82-f3wx-p625 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
