GHSA-339v-266x-79xr: nebula-mesh: Host revocation is not durable - blocked/offboarded hosts can regain a valid certificateCVE-2026-53602
0

Nebula-mesh contains an authorization vulnerability where hosts that have been blocked or offboarded can regain valid certificates by re-enrolling or renewing certificates without proper status checks. The system does not enforce blocklist checks at certificate issuance or re-enrollment time, allowing blocked hosts to obtain fresh certificates. Additionally, certificate renewal does not verify whether the owning operator or CA is still active, enabling hosts from disabled operators to continue renewing certificates indefinitely. This issue affects nebula-mesh versions prior to 0.3.7.
