CVE-2023-6778Network attack vector

Stored XSS via unsanitized web input

Published Dec 18, 2023 · Updated Aug 2, 2024

Cross-site scripting in ClearML Server before 1.13.0 allows remote authenticated users to inject script content stored by the web application. The public advisory does not disclose the specific request handler, field, or sanitization operation responsible for persisting the payload. Exploitation requires access to the ClearML web interface and a victim viewing the affected content, enabling script execution in that user's session with limited confidentiality and integrity impact.
