Vulnerability from github – Published: 2026-02-02 12:31 – Updated: 2026-02-02 22:04

Summary

llama-index-core vulnerable to Uncontrolled Resource Consumption

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.

Severity ?

5.3 (Medium)
