GHSA-fmrf-6jv9-qjc7: LlamaIndex is vulnerable to Path Traversal attack through its ObsidianReader class
A vulnerability in the ObsidianReader class in LlamaIndex Readers Integration: Obsidian before version 0.5.1 from the run-llama/llama_index repository (versions 0.12.23 to 0.12.28) allows for arbitrary file read through symbolic links. The ObsidianReader fails to resolve symlinks to their real paths and does not validate whether the resolved paths lie within the intended directory. This flaw enables attackers to place symlinks pointing to files outside the vault directory, which are then processed as valid Markdown files, potentially exposing sensitive information.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
