CVE-2025-6208
MEDIUM5.3EPSS 0.02%llama-index-core vulnerable to Uncontrolled Resource Consumption
Published: 2/2/2026Modified: 2/3/2026
Description
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.
