Technical details
An HTML injection vulnerability exists in Capgo versions prior to 12.128.2 within the organization settings endpoint. The root cause is improper neutralization of user-supplied input in the 'organization name' field (CWE-79). An authenticated attacker can inject malicious HTML tags that are rendered in the browsers of other users, such as team members invited to the organization. This can be leveraged to perform open redirection or phishing attacks. Exploitation requires low administrative privileges to modify organization settings and interaction from a victim user who views the affected page. The issue is resolved in version 12.128.2.
