CVE-2026-44454
Command injection via dotfiles URI allows code execution when provisioning Coder workspaces.
Is CVE-2026-44454 being exploited?
Not confirmed. CVE-2026-44454 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-44454?
CVE-2026-44454 is rated High with a CVSS score of 8.1. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Arbitrary command execution in a provisioned workspace via crafted dotfiles_uri (including one-click deep-link), enabling code execution in user workspaces.
Immediate action required
- affected< 2.29.7
- affected>= 2.30.0 and < 2.30.2
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
