Name of the Vulnerable Software and Affected Versions
Coder versions prior to 2.29.17
Coder versions prior to 2.32.7
Coder versions prior to 2.33.8
Coder versions prior to 2.34.2
Description
The
AgentLogLine dashboard component uses the ansi-to-html library without the escapeXML: true setting and inserts the output using dangerouslySetInnerHTML. This allows HTML embedded in workspace agent log lines to be rendered as live markup because server-side sanitization fails to neutralize HTML metacharacters. An attacker with workspace-owner access can emit arbitrary HTML into agent logs, which is then rendered in the session of any user, including administrators, who views the workspace page. While Content Security Policy blocks inline scripts, this can be used to inject meta refresh redirects, style rules for UI redressing or CSS-based exfiltration, or external img beacons.Recommendations
Update to version 2.29.17 or later.
Update to version 2.32.7 or later.
Update to version 2.33.8 or later.
