CVE-2026-26933 (GCVE-0-2026-26933)

Vulnerability from cvelistv5 – Published: 2026-03-19 17:08 – Updated: 2026-03-19 17:52

Title

Improper Validation of Array Index in Packetbeat Leading to Denial of Service

Summary

Improper Validation of Array Index (CWE-129) in multiple protocol parser components in Packetbeat can lead Denial of Service via Input Data Manipulation (CAPEC-153). An attacker with the ability to send specially crafted, malformed network packets to a monitored network interface can trigger out-of-bounds read operations, resulting in application crashes or resource exhaustion. This requires the attacker to be positioned on the same network segment as the Packetbeat deployment or to control traffic routed to monitored interfaces.

Severity ?

5.7 (Medium)

CVE-2026-26940 (GCVE-0-2026-26940)

Vulnerability from cvelistv5 – Published: 2026-03-19 17:14 – Updated: 2026-03-19 17:48

Title

Improper Validation of Specified Quantity in Input in Kibana Leading to Denial of Service

Summary

Improper Validation of Specified Quantity in Input (CWE-1284) in the Timelion visualization plugin in Kibana can lead Denial of Service via Excessive Allocation (CAPEC-130). The vulnerability allows an authenticated user to send a specially crafted Timelion expression that overwrites internal series data properties with an excessively large quantity value.

Severity ?

6.5 (Medium)

Vulnerability from cvelistv5 – Published: 2026-03-19 17:11 – Updated: 2026-03-19 17:50

Title

Missing Authorization in Kibana Leading to Unauthorized Endpoint Response Action Configuration

Summary

Missing Authorization (CWE-862) in Kibana’s server-side Detection Rule Management can lead to Unauthorized Endpoint Response Action Configuration (host isolation, process termination, and process suspension) via CAPEC-1 (Accessing Functionality Not Properly Constrained by ACLs). This requires an authenticated attacker with rule management privileges.

Severity ?

6.5 (Medium)

CVE-2025-66566 (GCVE-0-2025-66566)

Vulnerability from cvelistv5 – Published: 2025-12-05 18:10 – Updated: 2025-12-05 18:27

Title

yawkat LZ4 Java has a possible information leak in Java safe decompressor

Summary

yawkat LZ4 Java provides LZ4 compression for Java. Insufficient clearing of the output buffer in Java-based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data. JNI-based implementations are not affected. This vulnerability is fixed in 1.10.1.

Severity ?

8.2 (High)
