CVE-2026-61462

mcp-gitlab contains a path traversal vulnerability in the job_id parameter of build/index.js that allows attackers to redirect GitLab API requests to arbitrary endpoints. Attackers can supply crafted job_id values like ../../../user to escape the intended path prefix and access arbitrary GitLab API resources using the operator's personal access token.
