Alert meAnalysisAIv1 – Mar 12, 2026
Everest EV charging software prior to version 2025.9.0 contains an improper pointer arithmetic flaw in error handling where integer values are concatenated to strings, allowing local operators with high privileges to read sensitive memory regions including heap and stack data. Public exploit code exists for this vulnerability. The flaw requires user interaction and is resolved in version 2025.9.0, though patches remain unavailable for affected earlier versions.

Affects Everest. EVerest is an EV charging software stack. Prior to version 2025.9.0, in several places, integer values are concatenated to literal strings when throwing errors. This results in pointers arithmetic instead of printing the integer value as expected, like most of interpreted languages. This can be used by malicious operator to read unintended memory regions, including the heap and the stack. Version 2025.9.0 fixes the issue.
