CVE-2026-77364: obsidian-tc: Default folder ACL is fail-open; .obsidian plugin secrets are readable by default
With a default configuration, an undefined readPaths/writePaths meant allow-all, the strictReadDefault flag was inert, and the .obsidian/.git/.trash control directories were denied only during enumeration — not on the direct request path. A caller could read .obsidian/plugins/*/data.json, exfiltrating plugin API keys and Obsidian Sync passwords (live-reproduced), as well as any other in-vault file by path.
