- CVE-2026-4429, 9 Apr 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. CVE record
- CVE-2026-33559, 27 Mar 2026
- WordPress Plugin "OpenStreetMap" provided by MiKa contains a cross-site scripting vulnerability. On the site with the affected version of the plugin enabled, a logged-in user with a page-creating/editing privilege can embed some malicious script with a crafted HTTP request. When a victim user accesses this page, the script may be executed in the user's web browser. CVE record
- CVE-2024-8991, 27 Sep 2024
- The OSM - OpenStreetMap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's osm_map and osm_map_v3 shortcodes in all versions up to, and including, 6.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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. CVE record
- CVE-2024-3604, 9 Jul 2024
- The OSM - OpenStreetMap plugin for WordPress is vulnerable to SQL Injection via the 'tagged_filter' attribute of the 'osm_map_v3' shortcode in all versions up to, and including, 6.0.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. CVE record
- CVE-2024-3603, 9 Jul 2024
- The OSM - OpenStreetMap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'osm_map' shortcode in all versions up to, and including, 6.0.3 due to insufficient input sanitization and output escaping on user supplied attributes such as 'theme'. 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. CVE record
- CVE-2022-4676, 30 May 2023
- The OSM WordPress plugin through 6.01 does not validate and escape some of its shortcode attributes, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attack. CVE record
What to do if you run OSM
If you run OSM, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
