CVE-2026-32933 is a high-severity Denial of Service (DoS) vulnerability affecting AutoMapper versions prior to 15.1.1 and 16.1.1 in .NET applications. An unauthenticated attacker can exploit this by providing a specially crafted, deeply nested object graph, leading to recursive method calls that exhaust stack memory and terminate the application process. With a CVSS score of 7.5 (High), this vulnerability has a network attack vector and low attack complexity, resulting in a high impact on availability. There is currently no evidence of active exploitation, nor are public exploit codes available in common databases like Metasploit or ExploitDB, and community discussion is minimal.
