Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack through improper validation of hardlink targets during tar extraction. An attacker can access or modify files outside the intended extraction directory by crafting a malicious tarball with a hardlink entry whose target is...

SUSE CVE-2026-42496

Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory. makespecialfile passes the tar header's linkname to symlink without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular...

node-tar: tar: node-tar: Arbitrary file creation via path traversal bypass in hardlink security check

A flaw was found in node-tar, a Node.js module for handling TAR archives. This vulnerability allows a remote attacker to bypass path traversal protections by crafting a malicious TAR archive. The security check for hardlink entries uses different path resolution logic than the actual hardlink...

UBUNTU-CVE-2026-56876

extract-zip does not validate symlink targets when extracting zip archives. When processing a malicious zip file containing a symlink with a relative path like '../../../../etc/passwd', extract-zip will extract the symlink without validation, allowing it to point outside the extraction directory...

EUVD-2026-39504

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.6, filebrowser builds the download-as-zip / download-as-tar archive entry names with filepath.ToSlash, which on a Linux host is a no-op for...

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...

CVE-2026-12565 Path Traversal (Zip-Slip) in unarchive module

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...

CVE-2026-45390

In OCaml-tar before 3.4.0, a crafted archive with ../ path segments in its name allows escaping the current working directory. This is not desired behavior, and tar1 rejects such extractions, but ocaml-tar decompresses it anyway. The impact is that it allows arbitrary file writes outside of the...

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...

OESA-2026-2678 perl-Archive-Tar security update

archive::Tar provides an object oriented mechanism for handling tar files. It provides class methods for quick and easy files handling while also allowing for the creation of tar file objects for custom manipulation. If you have the IO::Zlib module installed, Archive::Tar will also support...

Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : .NET vulnerabilities (USN-8420-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8420-1 advisory. It was discovered that .NET did not properly handle link resolution before file access. A local attacker could use this...

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...

BIT-PYTHON-2026-7774 tarfile.data_filter path traversal bypass allows writing outside the extraction directory

tarfile.datafilter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall to write files outside the...

BIT-PYTHON-MIN-2026-7774 tarfile.data_filter path traversal bypass allows writing outside the extraction directory

tarfile.datafilter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall to write files outside the...

Node.js Module node-tar < 7.5.10 Arbitrary File Overwrite

The version of node-tar installed on the remote host is prior to 7.5.10. It is, therefore, affected by a vulnerability: - node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the getfilteredattrs function tarfile.datafilter component that computes a symlink's directory before stripping trailing slashes. An attacker can write files outside the intended extraction directory by crafting...
