Twitter Feeds WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Twitter Feeds plugin for WordPress, affecting all versions through 1.0.0. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into pages. These scripts are executed when users access the affected pages.

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.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access or higher can use the TwitterFeeds shortcode and include a 'tweet_title' parameter with injected script content. Once the shortcode is processed, the injected script will execute when the page is viewed.

Remediation

No known patch is available for this vulnerability. Users are advised to review the vulnerability details and consider uninstalling the affected plugin.
