Command go env is documented as outputting a shell script containing the Go environment. However, go env doesn't sanitize values, so executing its output as a shell script can cause various bad bahaviors, including executing arbitrary commands or inserting new environment variables. This issue is relatively minor because, in general, if an attacker can set arbitrary environment variables on a system, they have better attack vectors than making "go env" print them out.

CVSS

Base score: 9.8
Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.84 %
Percentile among all scored CVEs: 57
Score date: 10/21/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
