CVE-2026-47699

A flaw was found in guest-components. This vulnerability allows an attacker to achieve container escape and gain unauthorized access to the underlying pod virtual machine. When unpacking a crafted Open Container Initiative OCI image layer, the archive extraction routine fails to restrict hard lin...

BIT-PYTHON-2026-87910 tarfile hardlink fallback ignores custom extraction filter rejection via None

When tarfile extracts a link on a system that doesn't support links, it falls back to extracting a member from the archive. In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was...

CVE-2026-87910

CVE-2026-87910 affects Python's tarfile module. When extracting a hardlink on a system without link support, tarfile falls back to extracting the referenced member from the archive. During this fallback, the extraction filter function is invoked twice—once for the extracted member and once with t...

CVE-2026-47699 Confidential Containers Guest Components image-rs: zip-slip-class arbitrary file write via absolute entry path in hardlink fallback

Confidential Containers Guest Components provides guest tools and components for confidential container workloads. From 0.16.0 until 0.20.0, a crafted OCI image layer can make imagers::stream::unpack::unpack create a hardlink outside its destination directory. In image-rs/src/stream/unpack.rs,...
