Machine-written summary

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

Jenkins MCP Server Plugin versions 0.84.v50ca_24ef83f2 and earlier lack permission checks in several MCP tools. An attacker with Item/Read permission can view the configured SCM of a job without Item/Extended Read, or trigger builds without Item/Build. An attacker without Overall/Read can list the names of configured clouds. Upgrade to version 0.86.v7d3355e6a_a_18 or later.
