Detailsinfo

A vulnerability, which was classified as critical, has been found in Go playground up to 0.0.0-20260924211604-6d73cff14c16. This issue affects an unknown part of the component Txtar Handler. The manipulation of the argument HOME with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A malicious txtar could escape the intended execution context and force arbitrary writes to the playground host's trusted filesystem. Disjointly, one of the three possible paths to invoke go vet on the playground host did not correctly restrict the execution environment. This permitted a Go process to make a read for an environment configuration file rooted in the playground host's $HOME. Together, a well-crafted go env file and the go vet invocation could lead to remote code execution in the playground host itself. This does not affect users of go.dev/play directly; however, it may affect independent deployments of golang.org/x/playground.

The advisory is shared at go.dev. The identification of this vulnerability is CVE-2026-94445 since 09/21/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available.

Applying the patch 0.0.0-20260924211604-6d73cff14c17 is able to eliminate this problem.
