Key points
- The vulnerability is CVE-2026-111399, rated high severity with a CVSS score of 8.5.
- It affects PT Norther Lights Production MapSVG versions from the earliest release through 8.16.1.
- The flaw allows SQL injection via improper neutralization of special elements in commands.
Site administrators using the MapSVG plugin must verify their version numbers immediately. The vulnerability identified as CVE-2026-111399 affects all versions of the software up to and including 8.16.1. According to the National Vulnerability Database, this issue allows for SQL injection attacks. No vendor patch has been confirmed in the source records. Users on version 8.16.1 or lower are currently exposed to this high-severity risk.
In plain English
SQL injection occurs when an application fails to filter special characters in user input. An attacker can trick the database into executing malicious commands instead of simple queries. In MapSVG, this happens because special elements in SQL commands are not properly neutralized. This allows for SQL injection as described in the vulnerability record. The source material does not specify further consequences or confirmed exploitation methods beyond the vulnerability type itself.
The background
The Common Weakness Enumeration classifies this as CWE-89, which covers improper neutralization of SQL commands. The National Vulnerability Database assigned this flaw a CVSS score of 8.5, placing it in the high severity range. The affected product is the mapsvg-lite-interactive-vector-maps plugin developed by PT Norther Lights Production. The issue spans from the initial release of the software through version 8.16.1, meaning a wide range of deployments are at risk.
What changes now
Administrators must treat this as an urgent exposure until a vendor update is released. Because no fix is confirmed, the primary defense is reducing the attack surface. Teams should review server logs for unusual database activity. If possible, restrict access to the plugin’s interactive features. Monitor for any official announcements from PT Norther Lights Production regarding a patched version. Do not assume older versions are immune, as the flaw exists in the entire version history listed.
Who needs to act first
Teams usually prioritize systems exposed to the internet or public-facing forms. Check whether the MapSVG plugin is active on any visitor-accessible pages. Back up the current database and site configuration before making any changes. If a hotfix becomes available, test it on a staging environment first to ensure compatibility. Reduce exposure by limiting input fields that feed into the map features until the vendor provides an update.
What to do and how to stay safe: MapSVG
- Identify all websites hosting MapSVG version 8.16.1 or earlier and document their exposure level.
- Implement web application firewalls or input validation rules to block common SQL injection patterns.
- Monitor database logs for unexpected queries or error messages indicating injection attempts.
- Wait for an official patch from PT Norther Lights Production before updating the main site.
