GHSA-43r2-c7g8-prc8: obsidian-tc (CVE-2026-77362)

Package	Ecosystem	Affected	Fixed in
obsidian-tc	npm	<1.3.1	1.3.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

obsidian-tc versions before 1.3.1 are affected. Bridge tools filtered only the items array against the read access list and passed other response fields through unfiltered, so a caller could infer or read data from notes outside its permitted set, including through task group counts, query result fields, and template listings. Upgrade to obsidian-tc 1.3.1 or later, which scrubs these fields and gates template listing on the read whitelist; as a workaround, disable the affected bridge tools.
