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.\n\n## Affected packages\n\n- `llama-index-core < 0.12.41`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `llama-index-core 0.12.41`","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
