{"id":"CVE-2026-114103","summary":"adm-zip 0.6.0 Decompression Bomb Guard Bypass via getDataAsync()","details":"adm-zip 0.6.0 contains a decompression bomb protection bypass that allows attackers to evade the maxOutputLength guard by targeting the asynchronous getDataAsync() path in methods/inflater.js. Attackers can craft ZIP entries with falsified small declared sizes and high-ratio DEFLATE payloads to exhaust memory in applications reading entries asynchronously.","aliases":["GHSA-c6fg-446q-cg94"],"modified":"2026-10-21T10:45:18.474351695Z","published":"2026-10-21T00:37:04.594Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114103.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114103.json"},{"type":"ADVISORY","url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-c6fg-446q-cg94"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114103"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/adm-zip-0.6.0-decompression-bomb-guard-bypass-via-getdataasync"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cthackers/adm-zip","events":[{"introduced":"2b4d84087d45344643e0183756e19191d52815cc"},{"fixed":"cb2cf9ba4c7c865db426e2de1997cb41194d9872"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0.6.0"},{"fixed":"0.6.1"}]}]}}],"versions":["v0.6.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114103.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
