Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache SkyWalking MCP (github.com/apache/skywalking-mcp) versions before 0.2.0 are affected by a server-side request forgery vulnerability triggered through the SW-URL header. The source gives few details on what an attacker must already have access to or what the forged requests can reach. Users should upgrade to version 0.2.0, which fixes the issue.
