{"id":"CVE-2025-6208","aliases":["GHSA-488g-hw5f-x29p","PYSEC-2026-1560"],"url":"https://o3.security/vulnerability/CVE-2025-6208","summary":"Uncontrolled Memory Consumption in run-llama/llama_index","details":"The `SimpleDirectoryReader` component in `llama_index.core` version 0.12.23 suffers from uncontrolled memory consumption due to a resource management flaw. The vulnerability arises because the user-specified file limit (`num_files_limit`) is applied after all files in a directory are loaded into memory. This can lead to memory exhaustion and degraded performance, particularly in environments with limited resources. The issue is resolved in version 0.12.41.","published":"2026-02-02T10:36:23.033Z","modified":"2026-07-15T01:49:20.005010542Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"llama-index-core","fixedVersion":"0.12.41"}],"fix":{"url":"https://github.com/run-llama/llama_index/commit/53614e2f7913c0e86b58add9470b3c900b6c60b2","label":"run-llama/llama_index@53614e2"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/7d722bb6-6567-4608-8b23-f95048d7605a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/6xxx/CVE-2025-6208.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-6208"},{"type":"FIX","url":"https://github.com/run-llama/llama_index/commit/53614e2f7913c0e86b58add9470b3c900b6c60b2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:20.005010542Z"}}
