CVE-2026-45407: Dokku: Git Credentials in .netrc Stored World-Readable Due to Premature touch

• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-26 · updated 2026-06-26
• Weakness: CWE-522

Description

Dokku is a docker-powered PaaS. Prior to 0.38.2, the git:auth command creates $DOKKU_ROOT/.netrc using bash's touch command, which applies the default umask of 0644. This pre-creation defeats the netrc binary's built-in 0600 permission setting, leaving git credentials readable by any local user who can traverse the dokku home directory. This vulnerability is fixed in 0.38.2.

Affected products

• dokku: before 0.38.2 — fixed in 0.38.2

How to fix

Upgrade to a fixed version: dokku 0.38.2. Check the vendor advisory for mitigations.
