- Summary
- Coder vulnerable to stored HTML injection via workspace agent logs in AgentLogLine component
- Details
-
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
AgentLogLinedashboard component instantiatedansi-to-htmlwithoutescapeXML: trueand inserted the result viadangerouslySetInnerHTMLso 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 enablesescapeXML: trueso HTML metacharacters are escaped before DOM insertion. No known workarounds are available. - Database specific
