Why it matters

CVE-2026-76228 is a command injection vulnerability in Renovate's Gradle Wrapper artifact handling. Defenders should prioritize verifying exposure, especially in deployments where allowScripts is disabled, and consider compensating controls or monitoring to mitigate potential risks. The vulnerability requires verification from official sources, and its impact and remediation are still being assessed.

• Potential for arbitrary command execution in the Renovate runtime
• Need for verification of exposure in Renovate deployments
• Possible requirement for compensating controls or monitoring
• Importance of updating to a fixed version of Renovate

Technical summary

Renovate versions >=32.124.0 and before 42.68.5 contain a command injection vulnerability in Gradle Wrapper artifact handling. An attacker can exploit this by introducing a malicious gradle-wrapper.properties file into a repository that Renovate scans, potentially leading to arbitrary command execution in the Renovate runtime. The vulnerability requires verification from official sources, and its impact and remediation are still being assessed. The issue occurs even when allowScripts is disabled, and defenders should prioritize verifying exposure and consider compensating controls or monitoring.
