CVE-2026-55206

CVE-2026-55206 (py7zr) affects the Python-based 7z library py7zr. The root cause is an O(n^2) cumulative-sum implementation in PackInfo._read() (archiveinfo.py) that parses attacker-controlled numstreams from archive headers. This causes excessive CPU usage during SevenZipFile.init() before extra...

CVE-2026-55195

py7zr is a Python-based library and utility to support 7zip archive compression, decompression, encryption and decryption. Prior to 1.1.3, py7zr's Worker.decompress extracted archive entries without tracking total decompressed size, allowing a crafted .7z file such as a 15.6 KB archive that expan...

Symlink Attack

Overview bbot is an OSINT automation for hackers. Affected versions of this package are vulnerable to Symlink Attack in the unarchive process when extracting zip or 7z archives containing symlink entries with a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. An...

Infinite loop

Overview org.webjars.npm:tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Infinite loop via the replace method. An attacker can cause the archive scanner to enter an infinite loop by providing a tar header with a negative base-256 encoded entry size...

CVE-2026-59874

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, tar.replace accepts a checksum-valid tar header with a negative base-256 encoded entry size, causing the archive scanner to make no progress while repeatedly parsing the same header. This issue is fixed in version 7.5.18...

PYSEC-2026-3719

BBOT's unarchive module rejects archives containing symlink entries before extraction, but for zip and 7z archives it failed to detect symlinks whose listing carries a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. Such an archive, downloaded and extracted...
