AI Powered Q&A
Can you explain this vulnerability to me?
The Events In City plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 3.0. This occurs because the plugin does not properly sanitize or escape user-supplied attributes in the 'org-events' shortcode, such as 'organizer_id', 'width', 'height', 'transparency', 'header', 'border', and 'layout'. These attribute values are directly concatenated into HTML attributes without using proper escaping functions, allowing authenticated users with contributor-level access or higher to inject malicious scripts that execute when other users view the affected pages.
How can this vulnerability impact me? :
This vulnerability allows attackers with contributor-level access or above to inject arbitrary web scripts into pages. These scripts execute whenever a user accesses the injected page, potentially leading to unauthorized actions such as stealing user credentials, session hijacking, defacement, or spreading malware. Because the attack is stored, the malicious code persists and affects all users who view the compromised content.
