How severe is GHSA-86rg-8hc8-v82p?

No CVSS score has been assigned to GHSA-86rg-8hc8-v82p yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-86rg-8hc8-v82p?

GHSA-86rg-8hc8-v82p affects the following packages: librenms/librenms (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-86rg-8hc8-v82p?

Update librenms/librenms to 25.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-86rg-8hc8-v82p is resolved across your whole dependency graph.

How do I detect GHSA-86rg-8hc8-v82p in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for librenms/librenms. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-86rg-8hc8-v82p if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-86rg-8hc8-v82p?

O3 pinpoints whether GHSA-86rg-8hc8-v82p is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-86rg-8hc8-v82p actively exploited in the wild?

No public exploit code has been indexed for GHSA-86rg-8hc8-v82p yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-86rg-8hc8-v82p?

GHSA-86rg-8hc8-v82p has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 13th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-86rg-8hc8-v82p published, and has it been updated?

GHSA-86rg-8hc8-v82p was published on October 13, 2025 and was last updated on October 14, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Summary

Reflected-XSS in report_this function in librenms/includes/functions.php

Details

Recently, it was discovered that the report_this function had improper filtering (htmlentities function was incorrectly used in a href environment), which caused the project_issues parameter to trigger an XSS vulnerability.

The Vulnerable Sink: https://github.com/librenms/librenms/blob/master/includes/functions.php#L444

PoC

GET project_issues=javascript:alert(document.cookie)

Impact

XSS vulnerabilities allow attackers to execute malicious scripts in users' browsers, enabling unauthorized access to sensitive data, session hijacking, or malware distribution.

Suggestion

It is recommended to filter dangerous protocols, e.g. javascript:/file:.
