Technical Analysis
Renovate versions prior to 44.60.1 contain an allowlist bypass vulnerability that permits repositories to set restricted environment variables by placing env inside a shared preset. Attackers who control an externally sourced preset can override critical environment variables in child processes on self-hosted instances, which may lead to privilege escalation or other severe impacts. The vulnerability affects versions >=0 and <44.60.1, including sub-ranges >=0 <15.5.0 and >=0 <10.5.0. The CVSS 4.0 score is 9.0, indicating critical severity.
Potential Impact
An attacker with control over an externally sourced preset can override sensitive environment variables in child processes on self-hosted renovate instances. This can lead to unauthorized code execution, privilege escalation, or compromise of the build environment, posing a critical security risk.
Mitigation Recommendations
A fix is available in renovate version 44.60.1. Users should upgrade to version 44.60.1 or later to remediate this vulnerability. No additional mitigation steps are indicated beyond applying the official patch.
