      <title>GHSA-8wc6-vgrq-x6cf — Child processes spawned by Renovate incorrectly have full access to environment variables</title>
      <link>https://db.gcve.eu/vuln/ghsa-8wc6-vgrq-x6cf</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; npm: renovate&lt;/p&gt;
&lt;p&gt;When Renovate spawns child processes, their access to environment variables is filtered to an allowlist, to prevent unauthorized access to privileged credentials that the Renovate process has access to.&lt;/p&gt;
&lt;p&gt;Since [42.68.1](https://github.com/renovatebot/renovate/releases/tag/42.68.1) (2025-12-30), this filtering had been **inadvertently removed**, and so any child processes spawned from these versions will have had access to any environment variables that Renovate has access to.&lt;/p&gt;
&lt;p&gt;This could lead to [insider attackers](https://docs.renovatebot.com/security-and-permissions/#execution-of-code-insider-attack) and [outside attackers](https://docs.renovatebot.com/security-and-permissions/#execution-of-code-outsider-attack) being able to exflitrate secrets from the Renovate deployment.&lt;/p&gt;
&lt;p&gt;It is recommended to rotate (+ revoke) any credentials that Renovate has access to, in case any spawned child processes have attempted to exfiltrate any secrets.&lt;/p&gt;
&lt;p&gt;## Impact&lt;/p&gt;
&lt;p&gt;Child processes spawned by Renovate (i.e. `npm install`, anything defined in [`postUpgradeTasks`](https://docs.renovatebot.com/configuration-options/#postupgradetasks) or [`postUpdateOptions`](https://docs.renovatebot.com/configuration-options/#postupdateoptions)) will have full access to the environment variables that the Renovate process has.&lt;/p&gt;
&lt;p&gt;This could lead to [insider attackers](https://docs.renovatebot.com/security-and-permissions/#execution-of-code-insider-attack) and [outside attackers](https://docs.renovatebot.com/securit…&lt;/p&gt;</description>
