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 version 0.5.2."}], "lastModified": "2025-07-30T20:01:47.780", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:llamaindex:llamaindex:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8AC070B3-926A-4B3C-B6F4-28DA4B0F1CFF", "versionEndExcluding": "0.5.2"}], "operator": "OR"}]}], "sourceIdentifier": "security@huntr.dev"}
