Advisory
Source description from Wordfence Intelligence, credited to Naoya Takahashi (nakko).
The OSM – OpenStreetMap plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to 6.1.15 (exclusive) due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
