Answer in brief
CVE-2026-55433 records a Medium severity (CVSS 5.4) vulnerability in Coder: Devcontainer recreate endpoint missing write authorization allows read-only roles to destroy containers. The current sources do not mark it as known exploited. The current feed maps coder/coder (generic), github.com/coder/coder/v2 (go), github.com/coder/coder/v2 (go), github.com/coder/coder/v2 (go) and additional mapped packages. Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the devcontainer recreate endpoint relied on route middleware that checked only `ActionRead` on the workspace and, unlike the sibling delete endpoint, performed no `ActionUpdate` check before triggering the destructive rebuild. Exploitation requires an existing low-privilege role with access to the target workspace. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 adds an explicit `ActionUpdate` authorization check before the agent is dialed like the delete endpoint. No known workarounds are available.
