Last modified
CVE-2025-32793 is a medium-severity vulnerability rated 4/10 on the CVSS scale. Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Versions 1.15.0 to 1.15.15, 1.16.0 to 1.16.8, and 1.17.0 to 1.17.2, are vulnerable when using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can leave the source node without encryption due to a race condition in how traffic is processed by Cilium. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
