CVE-2026-77301

A flaw was found in adm-zip, a JavaScript library for handling ZIP archives. The getData function in zipEntry.js allocates memory based on the declared uncompressed size in a ZIP entry's central directory without validating this value against the actual compressed data. A remote attacker can...

GHSA-7Q85-XJ36-VMFC adm-zip: Uncontrolled memory allocation via the declared uncompressed size (DoS)

Summary adm-zip allocates an entry's output buffer from the declared uncompressed size central-directory size field before validating it against the actual data. A tiny crafted ZIP that declares a huge uncompressed size forces a multi-gigabyte allocation from a few bytes. Impact On adm-zip 0.5.17...
