Last modified
CVE-2026-122130 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. CESNET ipfixcol2 2.3.0 before 2.9.0 contains an integer overflow vulnerability in the Forwarder output plugin that allows unauthenticated IPFIX exporters to overflow a heap buffer by wrapping uint16_t message length counters. Attackers can send near-65535-byte data sets and large templates to a collector forwarding over TCP to crash it and perform 2-byte writes to attacker-influenced addresses.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
