GHSA-FXHP-MV3V-67QP `oras-go` tar extraction: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution

Root cause The tar-extraction helper ensureLinkPath at content/file/utils.go:262-275 validates that a hardlink's target resolves inside the extract base, but then returns the original unresolved target string back to the caller: go func ensureLinkPathbaseAbs, baseRel, link, target string string,...

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...

PYSEC-2026-425 MLFlow path traversal vulnerability

A path traversal vulnerability exists in the extractarchivetodir function within the mlflow/pyfunc/dbconnectartifactcache.py file of the mlflow/mlflow repository. This vulnerability, present in versions before v3.7.0, arises due to the lack of validation of tar member paths during extraction. An...

perl-archive-tar: perl-archive-tar: Path traversal via crafted symlinks allows arbitrary file access

A flaw was found in perl-Archive-Tar. Versions before 3.08 for Perl are vulnerable to a path traversal issue. An attacker can craft a malicious tar archive containing symlinks with targets outside the intended extraction directory. This vulnerability allows the attacker to read or write to...

Summary Boxlite is a sandbox service that allows users to create lightweight virtual machines Boxes and run OCI containers within them. Boxlite allows users to specify the OCI image used by containers in the sandbox. However, when processing tar entries in OCI images, Boxlite does not account for...

Incus has arbitrary file read+write on host via templates/ symlink in malicious image

Summary A specially crafted image or instance backup can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Details For container images, internal/server/storage/utils.go calls archive.UnpackimageFile, destPath, .... The tar extraction pa...

Dokku is a docker-powered PaaS. Prior to 0.38.2, the git:from-archive and certs:add commands extract user-supplied tar/zip archives into temporary directories without sanitizing member paths or preventing symlink traversal. GNU tar creates symlinks during extraction and follows them for subsequen...

GHSA-QXVG-H7Q2-HCXH motionEye: LFI → pass‑the‑hash admin → unsafe restore → unauth action exec (RCE)

Summary A multi‑stage chain in motionEye leads to remote code execution. The chain combines: 1. Arbitrary file read LFI via the picture download endpoint for local motion cameras using absolute paths. 2. Pass‑the‑hash admin auth due to accepting request signatures computed with password hashes. 3...

dotnet: .NET: Local file tampering via link following vulnerability

A flaw was found in .NET's System.Formats.Tar library. When extracting a specially crafted TAR archive containing symbolic links, the TarFile.ExtractToDirectory method may incorrectly follow those links and write files outside the intended extraction directory. An attacker could exploit this issu...

go.qbee.io/transport: Symlink-chain path traversal in tar extraction (one level outside destination)

Impact The go.qbee.io/transport library is affected by a symlink-chain path traversal vulnerability in its extractTar routine. The library's path validation is strictly lexical and fails to account for on-disk symlinks created earlier in the extraction process. Consequently, a crafted tar archive...
