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, the "AgentLogLine" dashboard component instantiated "ansi-to-html" without "escapeXML: true" and inserted the result via "dangerouslySetInnerHTML" so HTML embedded in workspace agent log lines was rendered as live markup. Server-side sanitization did not neutralize HTML metacharacters. Exploitation requires a victim to view attacker-controlled agent logs in the dashboard. The fix in versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2 enables "escapeXML: true" so HTML metacharacters are escaped before DOM insertion. No known workarounds are available.
