The vulnerability, CVE-2024-58376, is a command injection flaw in Renovate's helmv3 manager. Attackers with commit access can exploit this by manipulating registryAliases keys in the renovate.json configuration. When Renovate processes these aliases, it constructs a helm repo add command. The value.name (which is the alias key) is directly inserted into this command without being properly quoted or escaped. This allows an attacker to inject shell metacharacters (e.g., ||, ;, $()) into the value.name, causing arbitrary commands to be executed during the helm repo add operation. The HelmV3ArtifactsManager.addRepository function (or a similarly named function responsible for adding Helm repositories based on aliases) is identified as vulnerable because it contains the code responsible for constructing and executing this insecure command. The evidence for this comes directly from the GitHub security advisory (GHSA-rqgv-292v-5qgr), which pinpoints the exact line of code in lib/modules/manager/helmv3/artifacts.ts where the unquoted input is used in the shell command.
