What fixes it

  • 1.3.1obsidian-tc, npmGitHubnpm install obsidian-tc@1.3.1

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Impact

Bridge tool results filtered only the items array against the read ACL and passed sibling fields through unfiltered: tasks_filter emitted groups whose counts reflected denied notes, makemd_query returned ...result siblings, and list_templates enumerated Templater template paths and parsed user-function bodies with no read-whitelist gate. A caller could infer or read data from notes outside its read ACL.

Patches

Fixed in 1.3.1. Upgrade to >= 1.3.1. All path-attributable fields are now scrubbed or fail-closed, and list_templates is gated on the read whitelist.

Workarounds

Disable the affected bridge tools (tasks_filter, makemd_query, list_templates) via tool visibility.
