{"id":"CVE-2026-57442","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-57442","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).","published":"2026-06-19T21:42:24Z","modified":"2026-07-20T21:46:38.486393644Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@bitbonsai/mcpvault","fixedVersion":"0.11.5"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/bitbonsai/mcpvault/security/advisories/GHSA-9c83-rr99-vfwj"},{"type":"PACKAGE","url":"https://github.com/bitbonsai/mcpvault"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-20T21:46:38.486393644Z"}}
