CVE-2026-88885
Description
A flaw was found in Renovate. This vulnerability, a command injection, allows attackers to execute arbitrary commands as the Renovate user. This occurs when the gomod manager processes unescaped dependency names in import-path update commands, specifically in binarySource=docker mode during Go module major version updates with postUpdateOptions gomodUpdateImportPaths enabled. By injecting shell metacharacters through malicious dependency names, an attacker can achieve arbitrary code execution.

Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
