CVE-2026-45419
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.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
