Technical Analysis
Rowboat through version 0.9.1 fails to validate custom MCP server and webhook URLs properly. This allows authenticated users to specify arbitrary destinations for these URLs. Exploiting this, attackers can direct requests to internal services or cloud metadata endpoints, resulting in server-side request forgery (SSRF) and enabling enumeration of internal network topology.
Potential Impact
Authenticated attackers can exploit this vulnerability to perform SSRF attacks by configuring arbitrary URLs in the application. This may lead to unauthorized access to internal services and cloud metadata endpoints, potentially exposing sensitive internal network information. The CVSS score of 5.3 indicates a medium impact level.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user permissions to prevent configuration of MCP server and webhook URLs or apply network-level controls to limit access to sensitive internal endpoints.
