PYSEC-2026-1795 pip's fallback tar extraction doesn't check symbolic links point to extraction directory

When extracting a tar archive pip may not check symbolic links point into the extraction directory if the tarfile module doesn't implement PEP 706. Note that upgrading pip to a "fixed" version for this vulnerability doesn't fix all known vulnerabilities that are remediated by using a Python versi...

Security update for kubevirt-1.6

This update for kubevirt-1.6 fixes the following issues: CVE-2026-9804: Symlink escape in the VMExport dir handler let an attacker controlling an exported PVC read sensitive files TLS keys, tokens, service-account creds from the exporter pod. bsc1266733 CVE-2025-14525: A VM reporting many...

OSEC-2026-10 opam install sandbox escape using symlinks

Summary Installing files through .install files do not check symlinks resolution of the target path, and so can bypass sandboxing. Exploit Let's imagine a test package whose test.install file looks like the following: shareroot: "test" "blah/pwnd" and test.opam file: opam-version: "2.0" install:...

PYSEC-2026-1120 Ansible symlink attack vulnerability

An absolute path traversal attack exists in the Ansible automation platform. This flaw allows an attacker to craft a malicious Ansible role and make the victim execute the role. A symlink can be used to overwrite a file outside of the extraction path...

PYSEC-2026-1401 Ansible galaxy-importer Path Traversal vulnerability

A path traversal vulnerability exists in Ansible when extracting tarballs. An attacker could craft a malicious tarball so that when using the galaxy importer of Ansible Automation Hub, a symlink could be dropped on the disk, resulting in files being overwritten...

PYSEC-2026-788 binwalk vulnerable to UNIX Symbolic Link (Symlink) Following

A vulnerability, which was classified as problematic, was found in ReFirm Labs binwalk up to 2.3.2. Affected is an unknown function of the file src/binwalk/modules/extractor.py of the component Archive Extraction Handler. The manipulation leads to symlink following. It is possible to launch the...

PT-2026-56690

Name of the Vulnerable Software and Affected Versions opam versions prior to 2.5.2 Description Installing files via .install files does not verify symlink resolution of the target path, which allows for the bypass of sandboxing. An attacker can use a malicious .install file in combination with a...

PT-2026-56478

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description On Unix systems, opening a file in an os.Root improperly follows symbolic links to locations outside of the Root. This occurs when the final path component of a...

Important: python3.14

Issue Overview: tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the...

GHSA-R35R-FPX2-JGR4 Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases

Summary The SQLite databases are created at predictable static paths in /tmp. Any user can therefore create a symlink at these paths in /tmp pointing to arbitrary files. The monitoring scripts then follows these symlinks and then creates their database at the symlink target. This becomes really...

Directory Traversal

Overview decompress is a package that can be used for extracting archives. Affected versions of this package are vulnerable to Directory Traversal and link following during archive extraction, where symlink and hardlink entries are created without checking their targets and the directory...

GHSA-W6XC-G9QJ-VP32 uucore: safe_traversal TOCTOU protection only enabled on Linux

The safetraversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use TOCTOU symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize...

GHSA-H444-6J9X-P8VH mv: symlinks expanded during cross-device move (resource exhaustion / data duplication)

When moving directories across filesystems, uutils mv dereferences symlinks inside the tree, copying their targets as real files/dirs instead of preserving the symlinks. GNU preserves symlinks by default. E.g. a etclink - /etc inside the source becomes a full copy of /etc at the destination...
