CyberRota Analysis

AI-Generated

The vulnerability affects InvoiceNinja v5-stable, where the "terms" field in invoices is rendered without proper HTML sanitization, allowing authenticated users to inject malicious HTML/JavaScript via the REST API. This can lead to cross-site scripting (XSS) attacks, enabling session cookie theft and potential account takeover for clients viewing the invoice. Organizations using this version of InvoiceNinja should prioritize patching this vulnerability to protect their users from exploitation.
