CVE-2026-29796
CriticalSummary
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to impersonate stations and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known charging station identifier and issue or receive OCPP commands as a legitimate charger.
Risk Assessment
The lack of authentication can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.
Recommendation
It is recommended to implement proper authentication mechanisms for WebSocket endpoints to prevent unauthorized access and data manipulation.

A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.
