      <title>CVE-2026-52831 — Nuclio: Unsanitized cron trigger event headers/body injected into CronJob shell command leads to persistent RCE</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-52831</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nuclio&lt;/p&gt;
&lt;p&gt;Nuclio is a &amp;#34;Serverless&amp;#34; framework for Real-Time Events and Data Processing. Prior to version 1.16.4, the Nuclio controller builds a curl invocation string for each cron trigger and stores it as the args of a Kubernetes CronJob container (/bin/sh, -c, &amp;lt;command&amp;gt;). Two fields in the trigger specification flow into this string without adequate sanitization: event.headers keys and event.body. This issue has been patched in version 1.16.4.&lt;/p&gt;</description>
