CVE-2023-26140
@excalidraw/excalidraw Cross-site Scripting vulnerability
Impact
### 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. ### References https://security.snyk.io/vuln/SNYK-JS-EXCALIDRAWEXCALIDRAW-5841658 https://github.com/excalidraw/excalidraw/pull/6728
