Libocpp · Libocpp · CVE-2025-59398
**Name of the Vulnerable Software and Affected Versions**
libocpp versions prior to 0.26.2
**Description**
The OCPP implementation in libocpp is susceptible to a denial of service (EVerest crash) when processing JSON input exceeding 255 characters.

**Recommendations**
Update libocpp to version 0.26.2 or later.
