CyberRota Analysis
AI-GeneratedThe vulnerability affects Coder's remote development environment provisioning via Terraform, where a bypass in the subdomain-based workspace app proxy allows unauthorized access to workspaces by exploiting a flaw in the CORS check. This could enable an attacker to manipulate a victim into visiting a malicious URL, potentially compromising sensitive data or resources. Organizations using affected versions should prioritize updating to the fixed versions (2.29.17, 2.32.7, 2.33.8, or 2.34.2) to mitigate this security risk.

Original NVD Description
Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2, Coder's subdomain-based workspace app proxy allowed the same-owner CORS check to be bypassed. When a workspace-name subdomain segment parsed as a UUID, the workspace was resolved by ID without confirming the URL's username matched the real owner, while the CORS middleware trusted the unverified username in the hostname. Practical exploitation requires subdomain app routing (wildcard hostname) enabled and a victim who visits the attacker's crafted app URL while authenticated. The fix in versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2 validates the subdomain username against the resolved workspace's actual owner and bases the same-owner CORS decision on the authoritative owner identity. No known workarounds are available.
