CVE-2026-49867Public exploitNetwork attack vectorHinoki check available

Stored XSS via unvalidated template SVG writes

Published Jul 15, 2026 · Updated Jul 15, 2026

Stored XSS in FIT2CLOUD DataEase before 2.10.23 allows remote authenticated users to execute script in a victim's browser session. Template and import flows pass Base64-decoded SVG data to StaticResourceServer, which writes it into a same-origin public directory without content validation. Exploitation requires template privileges and a victim to load the generated SVG; the script then acts with the victim's browser-session access.
