myLinksDump Stored Cross-Site Scripting Vulnerability for WordPress

A stored cross-site scripting vulnerability has been identified in the myLinksDump plugin for WordPress, affecting all versions through 1.6. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level access to inject arbitrary scripts into pages. These scripts are executed when users access the compromised pages. This vulnerability is present in multi-site installations where unfiltered HTML is disabled.

Impact

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