The chunked-upload handler (dash_uploader/httprequesthandler.py, dash_uploader/upload.py) trusts unsanitized, attacker-controlled upload parameters (e.g. flowTotalChunks) and does not enforce the documented max_file_size limit, allowing a remote, unauthenticated attacker to cause an out-of-memory (OOM) process crash (unbounded range(1, flowTotalChunks + 1) allocation), truncation of the target file to zero bytes (flowTotalChunks=0, where the all([]) == True quirk runs the file-assembly branch on zero chunks), permanent disk exhaustion (never-cleaned-up temporary directories per flowIdentifier), and a complete bypass of the documented max_file_size limit.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-670"],"references":["https://docs.python.org/3/library/functions.html#all","https://github.com/a1ohadance/CVE-2026-38361","https://github.com/advisories/GHSA-xp7f-v245-w3w8","https://github.com/fohrloop/dash-uploader","https://github.com/fohrloop/dash-uploader/blob/stable/dash_uploader/httprequesthandler.py"],"products":["fohrloop:dash-uploader"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-38361","score":0.02643,"percentile":0.85593,"date":"2026-11-01"},"kev":null,"osv":[{"id":"PYSEC-2026-37","url":"https://osv.dev/vulnerability/PYSEC-2026-37","summary":"","modified":"2026-05-20T09:18:56.225045Z","packages":[{"ecosystem":"PyPI","name":"dash-uploader","purl":"pkg:pypi/dash-uploader","ranges":[">=0.1.0 <0.7.0a1"],"fixed":["0.7.0a1"]}]}],"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).
