CVE-2026-45796: Coder allows organizations to provision remote development environments via Terraform

Routine

MEDIUM 6.5REMOTEUPGRADE

CVE-2026-45796 is a medium-severity flaw (CVSS 6.5) affecting coder. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Coder allows organizations to provision remote development environments via Terraform. Versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 are vulnerable to unauthenticated semi-blind Server-Side Request Forgery (SSRF) via the Azure instance identity endpoint (`POST /api/v2/workspaceagents/azure-instance-identity`). An external attacker can force the Coder server to issue HTTP GET requests to arbitrary internal or external host

Why this priority

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.

Affected: < 2.24.5 · >= 2.29.0 and < 2.29.13 · >= 2.30.0 and < 2.30.8 · >= 2.31.0 and < 2.31.12 · >= 2.32.0 and < 2.32.2 · >= 2.33.0 and < 2.33.3

Fixed in: 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, 2.33.3

Safe to downgrade to: a release before 2.29.0

1. Check installed version

apt-cache policy coder || rpm -q coder || coder --version

2. UPGRADE to 2.24.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade coder

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade coder

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.29.0 (Debian / Ubuntu)

apt-cache madison coder sudo apt install coder=<VERSION_BEFORE_2.29.0> sudo apt-mark hold coder

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list coder sudo dnf downgrade coder-<VERSION_BEFORE_2.29.0> sudo dnf versionlock add coder

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
