      <title>CVE-2026-26287 — External Secrets Operator: label enforcement bypass in webhook generator enables secret exfiltration</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-26287</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; external-secrets&lt;/p&gt;
&lt;p&gt;External Secrets Operator reads information from a third-party service and automatically injects the values as Kubernetes Secrets. Starting in version 0.10.0 and prior to version 1.3.2, a bug in the `webhook` generator initialization order incorrectly cleared the label-enforcement flag (`EnforceLabels`) after it was set, resulting in the provider-side check for `external-secrets.io/type=webhook` being skipped (and the operation to succeed while it should have failed with `secret does not contain needed label &amp;#39;external-secrets.io/type: webhook&amp;#39;. Update secret label to use it with webhook`. Version 1.3.2 contains a patch.&lt;/p&gt;</description>
