CVE-2026-17106

A flaw was found in moby/go-archive. The tar extraction routines in the component do not properly restrict filesystem operations to the intended destination directory. An attacker who controls the contents of an archive can exploit this by including symbolic links, allowing them to create or overwrite files at arbitrary locations on the system where the archive is being extracted. This could lead to unauthorized modification of system files or potentially arbitrary code execution.

Threats

Impact Important

CVE-2026-75593

A flaw was found in BuildKit, a toolkit for converting source code to build artifacts. A malicious client with valid permissions to access the BuildKit control API can craft a special upload request. This request allows files to escape from the BuildKit-controlled state directory, potentially leading to unauthorized modification or deletion of files on the system.

CVE-2026-17106 (GCVE-0-2026-17106)

Vulnerability from cvelistv5 – Published: 2026-08-18 18:35 – Updated: 2026-08-19 03:56

Title

Tar extraction in moby/go-archive can write outside the destination directory via link following

Summary

The tar extraction routines in moby/go-archive (Unpack, UnpackLayer, Untar/UntarUncompressed, and the ApplyLayer helpers) do not confine filesystem operations to the destination directory. The extractor decides where each archive entry lands using lexical string checks and then performs the filesystem operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of the destination directory. An attacker who controls the contents of an archive can create or overwrite files at arbitrary paths writable by the extracting process.

Severity

7.1 (High)

CVE-2026-75593 (GCVE-0-2026-75593)

Vulnerability from cvelistv5 – Published: 2026-08-19 20:06 – Updated: 2026-08-25 14:02

Title

BuildKit: Malicious client can bypass destination directory validation on local sources upload

Summary

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to 0.31.2, a custom client can produce such an upload request to the BuildKit daemon that files can escape from the BuildKit-controlled state directory. The client needs to have valid permissions to access BuildKit control API to issue builds, eg., bypass authentication, etc. This issue is fixed in version 0.31.2.

Severity

7.2 (High)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
