CVE-2024-45390Public exploitNetwork attack vector

JavaScript execution via interpolated template display name

Published Sep 3, 2024 · Updated Sep 3, 2024

Code injection in @blakeembrey/template before 1.2.0 allows attackers to execute JavaScript by controlling a template display name. The compile function interpolates the displayName argument directly into generated function source, which template then evaluates with the Function constructor. Reachability requires a consuming application to pass attacker-controlled data as the optional display name; injected JavaScript runs with that application's process privileges.
