cpython: python: Extraction filter bypass for linking outside extraction directory

A flaw was found in CPython's tarfile module. This vulnerability allows bypassing of extraction filters, enabling symlink traversal outside the intended extraction directory and potential modification of file metadata via malicious tar archives using TarFile.extractall or TarFile.extract with the...

CVE-2026-12565

The unarchive internal module's archive extraction commands perform no code-level validation on extracted file paths, relying entirely on the behavior of external tools e.g. GNU tar which varies by platform. While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extractio...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the getFiles process. An attacker can cause arbitrary files to be written outside the intended extraction directory on Windows systems by uploading files with specially crafted names containing Windows-style...

USN-8420-1: .NET vulnerabilities

It was discovered that .NET did not properly handle link resolution before file access. A local attacker could use this issue to perform unauthorized file tampering and write arbitrary files outside of the intended extraction directory. CVE-2026-45491 It was discovered that .NET did not properly...

CVE-2026-45380 bit7z: Path Traversal via Null Byte Injection from `gcount()` Off-by-One in `restoreSymlink()`

bit7z is a cross-platform C++ static library that allows the compression/extraction of archive files. Prior to version 4.0.12, a one-byte off-by-one error in SafeOutPathBuilder::restoreSymlink allows an attacker to craft a .7z archive that, when extracted with bit7z on any non-Windows platform,...

SharpCompress has directory traversal via directory entries in WriteToDirectory (zip slip variant)

Summary A path traversal vulnerability in IArchive.WriteToDirectory allows a malicious archive to create directories outside the intended extraction root. For TAR archives, this can be escalated to arbitrary file writes by chaining with a symlink entry, giving a full write primitive on the target...
