"summary": "<p><strong>Sensitive Information in Resource Not Removed Before Reuse in Logstash Leading to Access to Sensitive Information</strong></p>\n<p>Dependency on Vulnerable Third-Party Component (CWE-1395) exists in org.lz4:lz4-java decompression library used by logstash-integration-kafka plugin in Logstash that could allow an attacker to access sensitive information from previous buffer contents via Input Data Manipulation (CAPEC-153). Exploitation requires the attacker to produce specially crafted, malformed compressed input to a Kafka topic consumed by Logstash, causing the decompression process to expose residual data from reused output buffers that were not cleared between operations - CVE-2025-66566.</p>\n<p><strong>Affected Versions:</strong></p>\n<ul>\n<li>8.x: All versions from 8.15.0 up to and including 8.19.9</li>\n<li>9.x:\n<ul>\n<li>All versions from 9.0.0 up to and including 9.1.9</li>\n<li>All versions from 9.2.0 up to and including 9.2.3</li>\n</ul>\n</li>\n</ul>\n<p><strong>Affected Configurations:</strong><br>\nThis vulnerability is limited to Logstash deployments that have the logstash-integration-kafka plugin configured to consume from a Kafka topic to which the attacker can publish messages. The attacker requires network access to the Kafka cluster and sufficient Kafka-level permissions (e.g., Kafka ACLs, if configured) to publish messages to the target topic.</p>\n<p><strong>Solutions and Mitigations:</strong></p>\n<p>The issue is resolved in version 8.19.10, 9.1.10, 9.2.4.</p>\n<p><strong>For Users that Cannot Upgrade:</strong></p>\n<p>The attacker requires network access to the Kafka cluster and sufficient Kafka-level permissions (e.g., Kafka ACLs, if configured) to publish messages to the target topic.</p>\n<p>Manually update the logstash-integration-kafka plugin to version 11.8.1 or higher using: bin/logstash-plugin update logstash-integration-kafka</p>\n<p><strong>Severity:</strong> CVSSv3.1: Medium ( 5.9 ) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N<br>\n<strong>CVE ID</strong>: CVE-2025-66566<br>\n<strong>Problem Type:</strong> CWE-226 - Sensitive Information in Resource Not Removed Before Reuse<br>\n<strong>Impact:</strong> CAPEC-153 - Input Data Manipulation</p>\n <p><small>1 post - 1 participant</small></p>\n <p><a href=\"https://discuss.elastic.co/t/logstash-8-19-10-9-1-10-9-2-4-security-update-esa-2026-06/385531\">Read full topic</a></p>",
