{"id":"CVE-2026-126938","summary":"Zipline before 4.6.4 Upload Quota Bypass via Forged Content-Range Headers","details":"Zipline before 4.6.4 contains a resource allocation vulnerability that allows authenticated users to bypass chunked-upload size and quota checks by forging Content-Range offsets and totals. Attackers can send tiny chunks to the partial upload endpoint with large declared offsets, causing the server to create oversized files and exhaust disk space.","aliases":["GHSA-fp8p-hf8g-fw65"],"modified":"2026-11-15T02:46:22.033372939Z","published":"2026-11-13T09:34:39.833Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126938.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-770"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126938.json"},{"type":"ADVISORY","url":"https://github.com/diced/zipline/security/advisories/GHSA-fp8p-hf8g-fw65"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126938"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zipline-before-4.6.4-upload-quota-bypass-via-forged-content-range-headers"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/diced/zipline","events":[{"introduced":"0"},{"fixed":"1e26037f455530c0767fcd9d5b2e1fcce93c6aa7"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"4.6.4"}]},{"source":"DESCRIPTION","range":[{"introduced":"0"},{"fixed":"4.6.4"}]}]}}],"versions":["v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.3","v4.5.2","v4.5.1","v4.5.0","v4.4.2","v4.4.1","v4.4.0","v4.3.2","v4.3.1","v4.3.0","v4.2.3","v4.2.2","v4.2.1","v4.2.0","v4.1.2","v4.1.1","v4.1.0","v4.0.2","v4.0.1","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-126938.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
