CVE-2025-10253Public exploitNetwork attack vector

Stored XSS via unsanitized SVG uploads

Published Sep 11, 2025 · Updated Sep 11, 2025

Stored XSS in openDCIM 23.04 allows remote authenticated users to execute scripts in other users' browsers via uploaded SVG files. The uploadifive.php path stores the Filedata SVG in a web-accessible location without removing embedded script elements or blocking the active format. An authenticated user must upload the SVG and another user must view it, where the script runs in that viewer's application context and can access session data.
