CVE-2026-101894 @xhmikosr/decompress: Path traversal via symlink chain

The decompress package for Node.js extracts archives. Prior to 10.2.2 and 11.1.4, the default decompressinput, output API relies on lexical containment checks that do not account for the kernel following a planted symlink chain. An attacker can supply a crafted archive containing chained symlink...

CVE-2026-101894

The decompress package for Node.js is vulnerable to a path traversal flaw due to inadequate lexical containment checks. An attacker can provide a crafted archive with chained symlink entries to bypass directory restrictions, allowing them to read or write files outside the intended output directo...

CVE-2026-85731

A flaw was found in oras-go, a Go library for managing OCI Open Container Initiative artifacts. A remote attacker can exploit a symlink-chain bypass vulnerability during tar extraction of OCI layers. This allows a malicious archive to create or overwrite any file writable by the process outside t...

CVE-2026-85731

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2 , the content/file.Store extraction of OCI layers marked with io.deis.oras.content.unpack=true is vulnerable to an arbitrary file-write outside the store's working directory. The root cause lies in the pushDir path: extractTarDire...

CVE-2026-55828 qbee transport: Symlink-chain path traversal in tar extraction (one level outside destination)

qbee transport is a remote access transport protocol implementation. Prior to 1.26.25, the extractTar routine uses strictly lexical path validation that does not account for on-disk symlinks created earlier in the extraction process. A crafted tar archive can use a symlink chain to write or...

CVE-2026-55828

go.qbee.io/transport , a remote access transport protocol implementation, is affected by a symlink-chain path traversal in its extractTar routine prior to v1.26.25 . The root cause is that path validation is strictly lexical and does not account for on-disk symlinks created earlier during extract...
