CVE-2024-12910:
LlamaIndex vulnerability analysis and mitigation
Overview
A vulnerability has been identified in the KnowledgeBaseWebReader class of the run-llama/llama_index repository (latest version) that allows attackers to cause a Denial of Service (DoS) condition. The vulnerability was disclosed on March 20, 2025, and is tracked as CVE-2024-12910 (NVD).
Technical details
The vulnerability exists in the get_article_urls method of the KnowledgeBaseWebReader class. When an attacker controls a URL variable to contain the root URL, it triggers infinite recursive calls to the get_article_urls method, leading to system resource exhaustion. The vulnerability has been assigned a CVSS v3.0 base score of 4.2 (Medium) with the vector string CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H (NVD, Huntr).
Impact
The successful exploitation of this vulnerability results in a Denial of Service condition by exhausting system resources through infinite recursive calls, potentially leading to application crashes (NVD).
Mitigation and workarounds
A fix has been implemented by adding a maxdepth parameter to prevent infinite recursion in the getarticleurls method. The patch is available in the repository commit 159ce485a1168100bb219dc1b93133f1121579d9 ([Github Commit](https://github.com/run-llama/llamaindex/commit/159ce485a1168100bb219dc1b93133f1121579d9)).
