LibreNMS 1.46 contains an authenticated SQL injection vulnerability in the MAC accounting graph endpoint that allows remote attackers to extract database information. Attackers can exploit the vulnerability by manipulating the 'sort' parameter with crafted SQL injection techniques to retrieve sensitive database contents through time-based blind SQL injection.
CVE-2020-36947
Score 7.1 from GitHub Security Advisory (severity: HIGH) published 2026-01-27. NVD baseline CVSS 7.1; sources differ by 0.0.
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
