CVE-2026-57441
Published:July 20, 2026
Updated:August 02, 2026
On case-insensitive filesystems (macOS, Windows), PathFilter compiled its deny-list patterns case-sensitively and matched the path verbatim, so names like ".Git/config", ".GIT/config", or ".oBsIdIaN/secrets.md" slipped past the ".git"/".obsidian"/"node_modules" restriction while the OS opened the real file. On Windows, trailing dots/spaces (".git./config", ".git /config") bypassed it the same way. Affects both "isAllowed" (read/write/move/search) and "isAllowedForListing". Vault-root ".." containment is NOT affected. Fixed in 0.11.4 by case-insensitive matching plus per-segment canonicalization before the deny-list check. Reported privately by novice-22.
