ePaperFlip Publisher Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the ePaperFlip Publisher plugin for WordPress, affecting all versions through 1. This issue arises from inadequate input sanitization and output escaping on the 'publicationid' attribute of the 'epaperflip_embed' shortcode, allowing authenticated attackers with Contributor-level access and above to inject arbitrary scripts. These scripts execute when a user accesses the compromised page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
