Local file disclosure via unchecked hardlinks
Published Jul 7, 2025 · Updated Jul 7, 2025
Path traversal in LlamaIndex Obsidian Reader before 0.5.2 allows local users to read files outside a configured vault through hardlinks. ObsidianReader.load_data() resolves each discovered path and checks its string prefix against the vault, but affected releases never reject a hardlink whose directory entry aliases an outside file. Exploitation requires the ability to place a hardlink in the processed vault; exposure is limited to files readable by the LlamaIndex process.
