A fix is available — apply it.

Renovate before 44.14.7 contains a command injection vulnerability in the Maven Wrapper manager that allows attackers to execute arbitrary commands by specifying a malicious distributionType parameter in maven-wrapper.properties. Attackers can inject shell commands through unescaped distributionType values to achieve remote code execution when Renovate processes Maven Wrapper updates in binarySource=docker mode.
