Top RCE Vulnerabilities A remote code execution (RCE) vulnerability is a software flaw that lets an attacker run their own code on a target system from a remote location. Exploiting vulnerabilities like this is now the most common way attackers get in: it was the initial access vector in 31% of breaches in Verizon’s 2026 Data Breach Investigations Report (DBIR), up from 20% the year before, and the median time to fully patch rose from 32 to 43 days.
