CVE-2025-28380Public exploitNetwork attack vector

Session-token theft via unsanitized iframe sources

Published Jun 13, 2025 · Updated Oct 27, 2025

Cross-site scripting in OpenC3 COSMOS before 6.0.2 allows remote attackers to execute scripts through a crafted Documentation tool URL. The Documentation tool and Telemetry Viewer bind user-controlled URL or template values directly to iframe source attributes while the page policy permits script execution. A logged-in user must open the malicious link or saved dashboard; the script can read the session token and invoke application functions as that user.
