CVE-2026-27957: Coolify: Authenticated RCE via command injection in CA certificate management feature

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.81% (FIRST EPSS); higher than 57.3% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: coollabsio coolify 4.0.0-beta.464.

Low priority for now. Upgrade to coollabsio coolify 4.0.0-beta.464 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, an authenticated command injection vulnerability in the CA Certificate management feature allows any authenticated user to execute arbitrary commands as the configured SSH user on the managed server host. As the SSH user typically would have to either be root or part of the docker group for Coolify to function as intended, this provides complete compromise of the managed server and associated docker containers. This vulnerability is fixed in 4.0.0-beta.464.
