SCA: security update for librenms/librenms (GHSA-h3rv-q4rq-pqcv)

critical Tenable Self-Hosted Container Security Plugin ID 437838

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring tool. Versions 25.12.0 and below
 contain an SQL Injection vulnerability in the ajax_table.php endpoint. The application fails to properly
 sanitize or parameterize user input when processing IPv6 address searches. Specifically, the address
 parameter is split into an address and a prefix, and the prefix portion is directly concatenated into the
 SQL query string without validation. This allows an attacker to inject arbitrary SQL commands, potentially
 leading to unauthorized data access or database manipulation. This issue has been fixed in version 26.2.0.
 (CVE-2026-26988)
