{"id":"CVE-2025-1752","aliases":["GHSA-7c85-87cp-mr6g","PYSEC-2026-1554"],"url":"https://o3.security/vulnerability/CVE-2025-1752","summary":"Denial of Service in run-llama/llama_index","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.","published":"2025-05-10T13:21:30.866Z","modified":"2026-08-12T03:51:35.762859430Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"llama-index","fixedVersion":"0.12.21"}],"fix":{"url":"https://github.com/run-llama/llama_index/commit/3c65db2947271de3bd1927dc66a044da385de4da","label":"run-llama/llama_index@3c65db2"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/cd7b9082-7d75-42e4-84f5-dbee23cbc467"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/1xxx/CVE-2025-1752.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1752"},{"type":"FIX","url":"https://github.com/run-llama/llama_index/commit/3c65db2947271de3bd1927dc66a044da385de4da"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.762859430Z"}}
