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.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-674"],"references":["https://github.com/run-llama/llama_index/commit/3c65db2947271de3bd1927dc66a044da385de4da","https://huntr.com/bounties/cd7b9082-7d75-42e4-84f5-dbee23cbc467","https://huntr.com/bounties/cd7b9082-7d75-42e4-84f5-dbee23cbc467"],"products":["llamaindex:llamaindex"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-1752","score":0.00521,"percentile":0.44283,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7c85-87cp-mr6g","url":"https://osv.dev/vulnerability/GHSA-7c85-87cp-mr6g","summary":"LlamaIndex Vulnerable to Denial of Service (DoS)","modified":"2026-07-07T17:56:51.058808077Z","packages":[{"ecosystem":"PyPI","name":"llama-index","purl":"pkg:pypi/llama-index","ranges":[">=0.12.15 <0.12.21"],"fixed":["0.12.21"]}]},{"id":"PYSEC-2026-1554","url":"https://osv.dev/vulnerability/PYSEC-2026-1554","summary":"LlamaIndex Vulnerable to Denial of Service (DoS)","modified":"2026-07-07T17:46:53.695420508Z","packages":[{"ecosystem":"PyPI","name":"llama-index","purl":"pkg:pypi/llama-index","ranges":[">=0.12.15 <0.12.21"],"fixed":["0.12.21"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
