LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring tool. Prior to version 25.11.0, a weak password policy vulnerability was identified in the user management functionality of the LibreNMS application. This vulnerability allows administrators to create accounts with extremely weak and predictable passwords, such as 12345678. This exposes the platform to brute-force and credential stuffing attacks. This issue has been patched in version 25.11.0.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
