CVE-2022-2015Network attack vector

Stored script execution via malformed diagram nodes

Published Jun 8, 2022 · Updated Aug 3, 2024

Stored XSS in draw.io before 19.0.2 allows remote attackers to run script in another user's session when a crafted diagram is opened. The mxCellCodec decoder accepted malformed XML cell values and HTML-bearing node names without enforcing the expected Element type before rendering. Exploitation requires a recipient to open the crafted diagram, after which script runs in the editor's security context.
