Vulnerability from fkie_nvd - Published: 2026-01-14 10:16 - Updated: 2026-06-17 10:10
Severity
6.5 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Improper Validation of Array Index (CWE-129) in Packetbeat’s MongoDB protocol parser can allow an attacker to cause Overflow Buffers (CAPEC-100) through specially crafted network traffic. This requires an attacker to send a malformed payload to a monitored network interface where MongoDB protocol parsing is enabled.
