Summary
A flaw was found in Renovate. This command injection vulnerability occurs when Renovate processes Gradle Wrapper updates.
An attacker can introduce a malicious `gradle-wrapper.properties` file into a scanned repository, where a specially crafted `distributionUrl` containing shell command substitution syntax can lead to arbitrary code execution within the Renovate runtime. This allows an attacker to execute unauthorized commands on the system running Renovate.
Red Hat does not ship or use an affected version of Renovate. Red Hat severity: Moderate — CVSS 6.7 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Weakness: CWE-78.

Mitigation checklist
- Red Hat products are not affected (see statement). Upstream, the issue is resolved by upgrading Renovate to 42.68.5 or later (or Mend renovate-ce/renovate-ee to 13.3.0); it can also be mitigated by restricting repository write access so untrusted users cannot introduce a malicious gradle-wrapper.properties.
