CVE-2018-18558 is a medium-severity vulnerability affecting Espressif ESP-IDF versions 2.x and 3.x before 3.0.6 and 3.1.x before 3.1.1. It involves insufficient input validation in the 2nd stage bootloader, allowing a physically proximate attacker to bypass secure boot and execute arbitrary code by overwriting a bootloader code segment. The attack requires physical access and is more complex if flash encryption is enabled, but can lead to high impact in terms of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
