CVE-2026-45419
CVE-2026-45419 — DataEase: Arbitrary File Write Vulnerability
DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase template saves call TemplateManageService#save, StaticResourceServer#saveFilesToServe, and the /de2api/templateManage/save endpoint with attacker-controlled staticResource names and Base64 content, allowing path traversal and arbitrary file writes because only / was used when extracting the file name. This issue is fixed in version 2.10.23.
