CVE-2026-109402
MediumCVSS 6.3Summary
In conductor-oss conductor 3.22.0, the MCPService.listTools function in MCPService.java (MCP Service component) improperly handles the mcpServer argument, leading to Server-Side Request Forgery (SSRF). The attack can be initiated remotely, and the exploit has been made public.
Risk Assessment
A remote attacker can force the server to make requests to arbitrary network resources, potentially accessing internal services or leaking data. The public exploit increases the risk of rapid exploitation.
Recommendation
Update conductor-oss conductor to a version where the vulnerability is fixed and restrict manipulation of the mcpServer argument. Until patched, review and limit access to the MCP Service functionality.
