Severity ?
4.7 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L
Summary
EVerest is an EV charging software stack, and EVerest libocpp is a C++ implementation of the Open Charge Point Protocol. In libocpp prior to version 0.30.1, pointers returned by the `strdup` calls are never freed. At each connection attempt, the newly allocated memory area will be leaked, potentially causing memory exhaustion and denial of service. Version 0.30.1 fixes the issue.
