Name of the Vulnerable Software and Affected Versions EVerest versions prior to 2026.02.0

Description EVerest is an EV charging software stack. A flaw exists in IsoMux certificate filename handling due to an off-by-one check. This can lead to a stack-based buffer overflow when a filename length equals MAX FILE NAME LENGTH (100). A crafted filename within the certificate directory can overflow file names[idx], potentially corrupting stack state and enabling code execution.

Recommendations Versions prior to 2026.02.0 should be updated to version 2026.02.0 or later.
