CVE-2026-93325: Docker Buildx bake entitlement consent bypass with --progress=rawjson

CVE-2026-93325 · Severity: info · Published 2026-11-03

Docker Buildx is a tool that builds container images. When using the bake command with the --progress=rawjson flag, a security consent check is bypassed that normally requires users to explicitly approve when a build accesses files outside its working directory. An attacker who tricks a user into running bake with untrusted build definitions and this flag could gain unauthorized access to sensitive files on the system.

Technologies: Docker Buildx. Vendors: Docker.

Quick answers

Is CVE-2026-93325 exploited in the wild?
No. Junglewise Threat Intelligence has no report of CVE-2026-93325 being exploited in the wild.
How severe is CVE-2026-93325?
Informational severity, published 3 November 2026.
Which products and versions are affected?
Docker Buildx >=0.21.0 before 0.37.2.
Is there a fix for CVE-2026-93325?
Yes: fixed in v0.37.2. Until then: Do not run bake with --progress=rawjson on untrusted build definitions; use a different progress mode to ensure the consent gate is enforced. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.
How is CVE-2026-93325 attacked?
It is attacked with local access, in a software library.
Am I affected by CVE-2026-93325?
Check whether you run Docker Buildx at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • Fixed in: v0.37.2

Do not run bake with --progress=rawjson on untrusted build definitions; use a different progress mode to ensure the consent gate is enforced.

Technical details

Buildx bake has a filesystem entitlement consent gate that prompts users or requires the --allow flag before builds can access files outside the working directory. Under --progress=rawjson mode, this consent check is skipped, allowing unauthorized filesystem access. The vulnerability affects versions >=0.21.0 and requires the attacker to convince a user to run bake with an untrusted definition and the --progress=rawjson flag; it was fixed in v0.37.2.

Affected products

  • Docker Buildx >=0.21.0 before 0.37.2
