The vulnerability arises due to inappropriate secure coding measures, specifically the lack of proper implementation of the max_depth parameter in the get_article_urls function. This allows an attacker to exhaust Python's recursion limit through repeated function calls, leading to resource consumption and ultimately crashing the Python process.\n\n## Affected packages\n\n- `llama-index >= 0.12.15, < 0.12.21`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `llama-index 0.12.21`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
