Summary

The Extensions for Leaflet Map plugin for WordPress, in all versions up to and including 5.4, is affected. An unauthenticated attacker who can control a GeoJSON data source used by a public map on the site could inject malicious scripts that run in the browsers of visitors who view the affected pages.

Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Read the original description

The Extensions for Leaflet Map plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'feature.properties[<template-token>]' parameter in all versions up to, and including, 5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that a site administrator has previously configured a public map using the [leaflet-map]+[leaflet-geojson]+[choropleth] shortcode combination whose GeoJSON src URL is one the attacker controls — for example, through compromise of an external data host, a subdomain takeover, or a site intentionally pointing at an attacker-hosted feed.
