@excalidraw/excalidraw Cross-site Scripting vulnerability
Impact
XSS vulnerability due to improperly sanitizing URLs of links that can be attached on canvas elements. This affects users of the npm package @excalidraw/excalidraw
provided it was deployed in environments where untrusted user input in drawings that are then shared with third parties is a concern. If you only hosted the editor in trusted environments, or sharing didn't take place, the impact is minimized.
Patches
Patch is available on version 0.15.3 and up (stable), or latest @excalidraw/excalidraw@next
(unstable releases).
Workarounds
No workaround without upgrading unless deployed in environments without untrusted user input.
