CVE-2026-88889: Renovate before 44.14.7 Command Injection via distributionType

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 64.3% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: renovatebot renovate 10.4.0, 15.4.0, 44.14.7.

Low priority for now. Upgrade to renovatebot renovate 10.4.0, 15.4.0, 44.14.7 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Renovate before 44.14.7 contains a command injection vulnerability in the Maven Wrapper manager that allows attackers to execute arbitrary commands by specifying a malicious distributionType parameter in maven-wrapper.properties. Attackers can inject shell commands through unescaped distributionType values to achieve remote code execution when Renovate processes Maven Wrapper updates in binarySource=docker mode.
