Descriptions

NVD
Wordfence

The FluentSMTP WordPress plugin before 2.2.3 does not sanitize or escape email content, making it vulnerable to stored cross-site scripting attacks (XSS) when an administrator views the email logs. This exploit requires other plugins to enable users to send emails with unfiltered HTML.

The FluentSMTP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via sending mail (thus adding the payload into the logs of sent emails) in versions up to 2.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
