What is CVE-2026-50529?

DataEase, an open source tool for data visualization and analysis, contains a vulnerability in its /de2api/share/proxyInfo share interface. Before version 2.10.24, the interface improperly generated and returned a valid X-DE-LINK-TOKEN without first validating the share password or ticket. This flaw allows attackers who possess a protected share UUID to acquire a valid token, enabling them to make subsequent API calls related to the share without proper authentication. This serious oversight compromises the integrity of share security, allowing unauthorized access to potentially sensitive information.
