EUVD-2026-83170

adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. Prior to 0.6.1, getData in zipEntry.js trusts an entry's central-directory uncompressed size and allocates output memory before validating that value against the actual compressed data and decompression result. A...

CVE-2026-92000

A flaw was found in adm-zip. A remote attacker could exploit this vulnerability by crafting a malicious ZIP archive containing highly compressible entries that declare a zero uncompressed size. This oversight prevents the application of zlib decompression output limits, leading to excessive memor...

EUVD-2026-80001

adm-zip versions 0.5.14 through 0.6.0 fail to apply zlib decompression output limits when ZIP entries declare zero uncompressed size. Attackers can craft malicious ZIP archives with highly compressible entries declaring zero size to exhaust memory and cause denial of service...

CVE-2026-92000 adm-zip 0.5.14 through 0.6.0 Denial of Service via Zero Declared Uncompressed Size

adm-zip versions 0.5.14 through 0.6.0 fail to apply zlib decompression output limits when ZIP entries declare zero uncompressed size. Attackers can craft malicious ZIP archives with highly compressible entries declaring zero size to exhaust memory and cause denial of service...

CVE-2026-92000

adm-zip versions 0.5.14 through 0.6.0 are vulnerable to a denial-of-service attack caused by failing to apply zlib decompression output limits when ZIP entries declare a zero uncompressed size . An attacker can craft a malicious ZIP archive containing highly compressible entries that declare zero...

EUVD-2026-61131

MobSF is a mobile application security testing tool used. Prior to 4.5.1, the unzip function in mobsf/StaticAnalyzer/views/common/sharedfunc.py logs that an archive member exceeding ZIPMAXUNCOMPRESSEDFILESIZE is being skipped but does not continue to the next member, so an authenticated user can...

CVE-2026-66913 Zip Bomb in Lookyloo Capture Upload Allows Denial of Service

Lookyloo did not enforce limits on the decompressed size of uploaded capture archives and compressed HAR files. An attacker could submit a specially crafted ZIP, gzip, or zlib-compressed capture containing data that expands to a very large size during processing. Because the application...

CVE-2026-61449

Grav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM\Installer. The size bound introduced in 2.0.1 sums the uncompressed size declared in each entry's ZIP central-directory header ZipArchive::statIndex'size' and rejects archives exceeding...

CVE-2026-61449

Summary of CVE-2026-61449 (Grav): Grav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM Installer. The new per-entry size bound (ZipArchive::statIndex()['size']) is summed against system.gpm.archive.max_uncompressed_size and blocks extraction before it, but the declared ...

CVE-2026-61449 Grav before 2.0.2 Decompression Bomb via Forged ZIP Size

Grav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM\Installer. The size bound introduced in 2.0.1 sums the uncompressed size declared in each entry's ZIP central-directory header ZipArchive::statIndex'size' and rejects archives exceeding...

CVE-2026-39244

A flaw was found in adm-zip. A remote attacker can exploit this vulnerability by providing a specially crafted ZIP file. The file's header can be manipulated to declare an extremely large uncompressed size, causing the application to allocate an excessive amount of memory. This excessive memory...

SUSE CVE-2026-39244

adm-zip before 0.5.18 is vulnerable to denial of service via a crafted ZIP file with a manipulated uncompressed size header field. In zipEntry.js line 103, Buffer.alloccentralHeader.size allocates memory based on the declared uncompressed size from the ZIP central directory header without...
