MEDIUMCVSS 5.3/10

Last modified

CVE-2026-114103 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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..
