CVE-2018-3737 describes a Regular Expression Denial of Service (ReDoS) vulnerability in the joyent sshpk library, triggered by parsing crafted invalid public keys. This high-severity vulnerability (CVSS 7.5) can lead to a denial of service (A:H) with low attack complexity (AC:L) and no user interaction required (UI:N), making it easily exploitable over the network (AV:N). While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, organizations using sshpk should still patch to mitigate this risk.
