Excalidraw vulnerable to XSS via Mermaid sequence diagram labels (KaTeX rendering)
### Impact `@excalidraw/excalidraw@0.18.0` depends on a Mermaid conversion package version that resolves to a Mermaid release affected by CVE-2025-54881 / GHSA-7rqq-prvp-x9jh. User-supplied Mermaid sequence diagram labels could trigger XSS through Mermaid’s KaTeX label rendering path. This is patched in `@excalidraw/excalidraw@0.18.1` by updating `@excalidraw/mermaid-to-excalidraw` to `2.2.2`, which uses a patched Mermaid 11 release. Moderate severity as this XSS requires manual user action - pasting unsafe Mermaid diagram into the Excalidraw editor. No semi-automated attack vector exists by default (such as accessing a link). ### Patches
- Обновитесь до 1.1.3
