CVE-2026-77362Network attack vectorHinoki check available

Authenticated disclosure via unfiltered bridge fields

Published Oct 13, 2026 · Updated Oct 13, 2026

Read-ACL bypass in obsidian-tc before 1.3.1 allows remote authenticated users to read denied-note data via bridge tools. tasks_filter filters items but exposes denied-note group counts, makemd_query passes sibling fields through, and list_templates returns template paths and user-function bodies without a read-whitelist check. Exposure requires enabled bridge tools connected to running Obsidian and a restrictive read ACL; the demonstrated consequence is unauthorized reading or inference, not note modification.
