If you use Obsidian, and especially if you use the new Canvas feature, you should update to the latest 1.1.9 release.
Last night I reported several security and privacy issues that have now been fixed.
See https://forum.obsidian.md/t/multiple-security-privacy-issues-in-canvas-malicious-website-can-access-internal-obsidian-uri/50400 for details.
Props to the Obsidian developers for the fast turnaround.
