CVE-2026-26988: LibreNMS: SQL Injection in ajax_table.php spreads through a covert data stream.

SQL Injection in IPv6 Address Search functionality via address parameter*

A SQL injection vulnerability exists 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.
