Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Scott Reilly Post-to-Post Links allows Stored XSS.This issue affects Post-to-Post Links: from n/a through 4.2.

The Post-to-Post Links plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 4.2 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. This only impacts multi-site installations and installations where unfiltered_html has been disabled.
