Severity

6.9 (Medium) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N CVSS Calculator

Summary

MCPVault: PathFilter restricted directories (.git/.obsidian/node_modules) only denied at vault root, not nested

Details

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).
