Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Flaw Remediation directly mitigates this CVE by identifying, patching, and deploying fixes for the improper input neutralization in the vulnerable AcuGIS Leaflet Maps WordPress plugin versions <=5.1.1.0.

prevent

Information Output Filtering prevents reflected XSS by encoding or filtering user inputs before inclusion in dynamically generated web pages, addressing the core neutralization failure.

prevent

Information Input Validation rejects or sanitizes malicious inputs containing XSS payloads before they are reflected in web page generation.

MITRE ATT&CK Enterprise TechniquesAI

T1204.001 Malicious Link Execution
An adversary may rely upon a user clicking a malicious link in order to gain execution.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
Why these techniques?

Reflected XSS is directly exploited via malicious links (T1204.001) to inject and execute arbitrary JavaScript (T1059.007) in the victim's browser.

NVD Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in David Ghedini AcuGIS Leaflet Maps mapfig-premium-leaflet-map-maker allows Reflected XSS.This issue affects AcuGIS Leaflet Maps: from n/a through <= 5.1.1.0.

Deeper analysisAI

CVE-2025-27278 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the AcuGIS Leaflet Maps WordPress plugin (mapfig-premium-leaflet-map-maker) developed by David Ghedini. The issue affects all versions from n/a through 5.1.1.0 and was published on 2025-03-03.

The vulnerability has a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating exploitation is possible by unauthenticated attackers over the network with low attack complexity, though it requires user interaction such as clicking a malicious link. Successful exploitation enables reflected XSS, allowing attackers to inject and execute arbitrary scripts in the context of the victim's browser, with low impacts on confidentiality, integrity, and availability within a changed scope.
