CVE-2018-1000015 — Jenkins Pipeline Nodes And Processes security vulnerability

Medium CVSS 4.9

On Jenkins instances with Authorize Project plugin, the authentication associated with a build may lack the Computer/Build permission on some agents. This did not prevent the execution of Pipeline `node` blocks on those agents due to incorrect permissions checks in Pipeline: Nodes and Processes plugin 2.17 and earlier.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
