Doc Text:
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.

Description OSIDB Bzimport 2026-08-19 14:19:23 UTC 
Renovate versions >=32.124.0 and before 42.68.5 (and Mend renovate-ce/renovate-ee before 13.3.0) contain a command injection vulnerability in Gradle Wrapper artifact handling. When Renovate processes Gradle Wrapper updates, it invokes a wrapper update command via a shell (e.g. /bin/sh -c ... ./gradlew :wrapper --gradle-distribution-url <value>). If an attacker supplies a malicious gradle-wrapper.properties whose distributionUrl contains shell command substitution syntax such as $(...), the shell evaluates it before Gradle parses the URL, resulting in arbitrary command execution in the Renovate runtime. Exploitation requires the attacker to introduce the malicious file into a repository that Renovate scans; the issue occurs even when allowScripts is disabled.
