CVE-2026-57442
Published:July 20, 2026
Updated:August 02, 2026
PathFilter's deny-list glob patterns are anchored, so ".git", ".obsidian", and "node_modules" were only blocked at the vault root. Nested copies inside the vault (e.g. "tools/cli/node_modules/...", "tools/somerepo/.git/config", a nested ".obsidian/") were fully traversable via isAllowed/isAllowedForListing. Impact: a nested ".git/config" (remote URLs / embedded tokens) and nested ".obsidian" contents could be read, under the same prompt-injection threat model as GHSA-j99q-93c9-h869 (an attacker influences the path an agent reads). It also caused nested "node_modules" to pollute the tag index (#128, the public symptom). Fixed in 0.11.5 by denying these restricted names at any path depth (matched case-insensitively as any path segment).
