      <title>CVE-2026-93539 — Unauthenticated GitRepo Spec Mutation via Fleet Git Webhook Receiver</title>
      <link>https://db.gcve.eu/vuln/cve-2026-93539</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; SUSE Rancher&lt;/p&gt;
&lt;p&gt;A vulnerability was discovered in Fleet&amp;#39;s Git webhook receiver (the gitjob webhook service). When a webhook secret is not configured, incoming webhook requests are accepted without verification, and processing a request can change the spec.pollingInterval field of a matching GitRepo resource in any namespace. A caller with network access to the webhook service and no Kubernetes credentials can therefore alter GitRepo configuration outside&lt;/p&gt;
&lt;p&gt;the namespaces they are authorized for.  This only affects SUSE Rancher Fleet 0.16 before 0.16.2, older versions are not affected.&lt;/p&gt;</description>
