CVE-2026-71464

Description

LaunchConfigurationBaseSerializer.scm_branch has no validate_scm_branch() leading-dash check, unlike Project/JobTemplate/JobLaunch serializers. Schedule and WFJT Node accept --upload-pack=/bin/id as scm_branch. Currently blocked at runtime by jobs.py:1502 ValueError check (defense-in-depth), but the API validation gap means sole reliance on a task-layer guard. Refactoring that guard away would promote this to RCE.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
