Security scanner finds minimal exploitable SSRF bugs in MCP servers

By PulseAugur Editorial · [1 sources] ·

A security researcher developed a static scanner to identify server-side request forgery (SSRF) vulnerabilities in MCP servers. After an initial scan of 36 public MCP servers yielded 482 findings, a manual review revealed that most were false positives. These included legitimate uses of functions like `exec()`, comments, and placeholder secrets. After refining the scanner to better distinguish exploitable SSRF from noise, a subsequent scan of the same servers resulted in only 28 findings, none of which were deemed exploitable. AI

    I scanned 36 public MCP servers for SSRF. 482 findings, 0 real bugs.

    <p>I built a small static scanner for MCP servers after I found a real SSRF bug in one of my own webhook routes. Then I ran it on 36 public MCP servers to see how bad the ecosystem looked.</p> <p>First result: 482 findings. Second result, after I read them: almost none were real.…
