{"id":"GHSA-7c85-87cp-mr6g","summary":"LlamaIndex Vulnerable to Denial of Service (DoS)","details":"A Denial of Service (DoS) vulnerability has been identified in the KnowledgeBaseWebReader class of the run-llama/llama_index project, affecting version ~ latest(v0.12.15). 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.","aliases":["CVE-2025-1752"],"modified":"2025-10-16T08:05:41.149134Z","published":"2025-05-10T15:30:28Z","database_specific":{"cwe_ids":["CWE-400","CWE-674"],"nvd_published_at":"2025-05-10T14:15:32Z","github_reviewed":true,"github_reviewed_at":"2025-05-12T20:16:19Z","severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1752"},{"type":"WEB","url":"https://github.com/run-llama/llama_index/commit/3c65db2947271de3bd1927dc66a044da385de4da"},{"type":"PACKAGE","url":"https://github.com/run-llama/llama_index"},{"type":"WEB","url":"https://huntr.com/bounties/cd7b9082-7d75-42e4-84f5-dbee23cbc467"}],"affected":[{"package":{"name":"llama-index","ecosystem":"PyPI","purl":"pkg:pypi/llama-index"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.12.15"},{"fixed":"0.12.21"}]}],"versions":["0.12.15","0.12.16","0.12.17","0.12.18","0.12.19","0.12.20"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/05/GHSA-7c85-87cp-mr6g/GHSA-7c85-87cp-mr6g.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
