Vulnerability from github – Published: 2026-09-10 15:33 – Updated: 2026-09-10 15:33

Details

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.

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\u0027s gradle/wrapper/gradle-wrapper.properties file before invoking the Gradle Wrapper CLI. In self-hosted deployments configured with binarySource=docker and allowedUnsafeExecutions=[\u0027gradleWrapper\u0027, ...], 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 \u0027gradleWrapper\u0027 from allowedUnsafeExecutions."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
