      <title>BIT-elk-2026-72632 — Observable Discrepancy in Kibana Fleet Leading to Disclosure of Elastic Agent Elasticsearch API Keys</title>
      <link>https://db.gcve.eu/vuln/bit-elk-2026-72632</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Bitnami: elk&lt;/p&gt;
&lt;p&gt;Observable Discrepancy (CWE-203) in Kibana Fleet can lead to information disclosure via Excavation (CAPEC-116). Fleet removes the Elasticsearch API key value of an enrolled Elastic Agent from the responses of its agent listing capability, but that capability accepted caller-supplied filter expressions over the stored field that holds the value, and evaluated them with Kibana&amp;#39;s own internal Elasticsearch privileges rather than the caller&amp;#39;s. Because the number of matching agents is reported back to the caller, the difference between a matching and a non-matching filter formed a side channel from which the full API key value could be reconstructed one character at a time with a short sequence of requests.&lt;/p&gt;</description>
