Phishing redirection via unsanitized organization names

Published Jul 8, 2026 · Updated Jul 8, 2026

HTML injection in Capgo before 12.128.2 allows remote authenticated users to redirect invited users through a crafted organization name. The organization settings page renders the organization name as HTML without sanitization, allowing an embedded link to target an attacker-controlled site. Exploitation requires an account, organization creation, a team invitation, and a recipient who opens the invitation and clicks the injected link.
