Summary

GlobaLeaks prior to version 5.0.89 performs only minimal validation on user-submitted support requests sent to the /api/support endpoint. As a result, arbitrary URLs can be included in support emails sent to administrators. Version 5.0.89 patches the issue.

Risk Assessment

An attacker can inject malicious or misleading links into messages delivered to administrators, facilitating phishing or social engineering against staff operating the system.

Recommendation

Upgrade GlobaLeaks to version 5.0.89 or later. Until patched, consider restricting access to the /api/support endpoint and verifying links in support requests.
