This flaw permits attackers to bypass path restrictions and access sensitive system files, such as /etc/passwd, by exploiting hardlinks. The vulnerability arises from inadequate handling of hardlinks in the load_data() method, where the security checks fail to differentiate between real files and hardlinks. This issue is resolved in llama-index-readers-obsidian version 0.5.2.\n\n## Affected packages\n\n- `llama-index-readers-obsidian < 0.5.2`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `llama-index-readers-obsidian 0.5.2`","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":34.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
