The Webpushr Push Notifications plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'webpushr notification title' and 'webpushr notification body' parameters in versions up to, and including, 4.39.0. This is due to insufficient input sanitization in the save send notification flag() function and missing output escaping in the wpp notification box() function, which concatenates raw post meta values directly into HTML attribute and textarea contexts. 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.
