CVE-2026-4429 PUBLISHED

OSM <= 6.1.15 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'marker_name' Shortcode Attribute

Assigner: Wordfence
Reserved: 19.03.2026 Published: 09.04.2026 Updated: 09.04.2026

The OSM – OpenStreetMap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'marker_name' and 'file_color_list' shortcode attribute of the [osm_map_v3] shortcode in all versions up to and including 6.1.15. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
