CVE-2026-88886Network attack vector

Command execution via unescaped Gradle distribution URL

Published Sep 10, 2026 · Updated Sep 10, 2026

Command injection in Mend.io Renovate before 44.14.7 allows remote authenticated users to execute commands through a crafted Gradle URL. The manager/gradle-wrapper module passes distributionUrl from gradle/wrapper/gradle-wrapper.properties to the Gradle Wrapper CLI without shell escaping. Exploitation requires a self-hosted instance with binarySource=docker and gradleWrapper allowed as an unsafe execution, and commands run with the Renovate process's privileges.
