MCPVault is a lightweight Model Context Protocol server for safe access to files in an Obsidian vault. Prior to 0.11.5, PathFilter in src/pathfilter.ts uses root-anchored deny-list patterns, so nested .git, .obsidian, and node_modules path segments do not match the restriction and pass both isAllowed() and isAllowedForListing(). An attacker who influences a path selected by an AI agent can traverse nested repository or Obsidian metadata, read remote URLs or embedded tokens, or cause nested node_modules content to pollute the listAllTags index. This issue is fixed in version 0.11.5.
