# CVE-2026-9594: WP Maps \<= 4.9.4 - Authenticated (Admin+) Stored Cross-Site Scripting via 'location\_messages' Parameter

- Severity: CVSS 4.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-06-06 · Updated: 2026-06-06

## Affected

- flippercode WP Maps – Google Maps,OpenStreetMap,Mapbox,Store Locator,Listing,Directory & Filters: through 4.9.4

## Description

The WP Maps – Google Maps,OpenStreetMap,Mapbox,Store Locator,Listing,Directory & Filters plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'location_messages' parameter in all versions up to, and including, 4.9.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the attacker to hold the custom wpgmp_manage_location capability, which is granted to administrators by default but can be assigned to lower-privileged roles via the plugin's Permissions screen.
