CVE-2026-119289

Zuke: githubWorkflow adopts any workflow run whose title matches its marker, so anyone who can dispatch the workflow can satisfy or block a release gate

Published Oct 30, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
Zuke is a code-first, strongly typed build automation system for Deno. Prior to 1.10.0, the @zuke/gh githubWorkflow(...) gate correlates a dispatched workflow run using only a display-title marker that is visible in the workflow run list and can be copied by another dispatcher. In configurations where the external workflow repository grants workflow_dispatch permission to a party not equally trusted by the releasing repository, an attacker can dispatch a run with the marker and cause the gate to adopt its conclusion without verifying the event, ref, or creation window. A passing substituted run can authorize an unvalidated release, while a failed or cancelled run can block a valid release, and the persisted adopted run ID preserves the substitution across build resume. This issue is fixed in version 1.10.0.
