Renovate is a dependency update automation tool. In versions before 44.14.7 (and in Mend Renovate CE/EE distributions before 15.4.0, and the mend-renovate-enterprise-edition Helm chart before 10.4.0), the manager/gradle-wrapper module does not escape the distributionUrl value read from a repository's gradle/wrapper/gradle-wrapper.properties file before invoking the Gradle Wrapper CLI. In self-hosted deployments configured with binarySource=docker and allowedUnsafeExecutions=['gradleWrapper', ...], a repository that supplies a crafted distributionUrl (for example, appending a shell metacharacter and command) can cause arbitrary commands to be executed as the Renovate user when Renovate processes a Gradle Wrapper update. The issue is fixed in Renovate 44.14.7; as a workaround, remove 'gradleWrapper' from allowedUnsafeExecutions.
