CVE-2025-66955Public exploitNetwork attack vector

Authenticated file disclosure via unchecked attachment paths

Published Mar 12, 2026 · Updated Mar 12, 2026

Local file inclusion in Asseco SEE Live 2.0 allows remote authenticated users to read host files through attachment-download APIs. The downloadAttachment and downloadAttachmentFromPath calls use the caller-controlled path parameter as a filesystem path, permitting absolute paths such as /etc/passwd. Low-privileged authentication is required, and the demonstrated effect is file disclosure without reported file modification or service interruption.
