Affected packages
• Maven io.jenkins.plugins:mcp-server: < 0.86.v7d3355e6a → fixed in 0.86.v7d3355e6a
Description
Jenkins MCP Server Plugin 0.84.v50ca_24ef83f2 and earlier does not perform permission checks in several MCP tools.
This allows to do the following:
• Attackers with Item/Read permission can obtain information about the configured SCM in a job despite lacking Item/Extended Read permission (`getJobScm`).
• Attackers with Item/Read permission can trigger new builds of a job despite lacking Item/Build permission (`triggerBuild`).
• Attackers without Overall/Read permission can retrieve the names of configured clouds (`getStatus`).
MCP Server Plugin 0.86.v7d3355e6a_a_18 performs permission checks for the affected MCP tools.
