CVE-2026-33009
EVerest: MQTT Switch-Phases Command Data Race Causing Charger State Corruptio
EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to C++ UB (potential memory corruption). This is triggered by an MQTT everest_external/nodered/{connector}/cmd/switch_three_phases_while_charging message and results in Charger::shared_context / internal_context accessed concurrently without lock. Version 2026.02.0 contains a patch.
