CVE-2026-9177

Server-Side Template Injection in SecureTransport's Apache Velocity mail templates

A Server-Side Template Injection (SSTI) vulnerability was identified 
in the mail template functionality of the Axway SecureTransport product in version 5.5-20260326. This 
flaw 
allows an attacker with admin privileges to inject arbitrary Java code expressions, which are 
executed server-side when the template is rendered (i.e., during email 
sending). Successful exploitation of this flaw allows an attacker to 
execute 
arbitrary code on the server that results in full host compromise.



This issue affects all Axway SecureTransport versions prior 5.5-20260528 update.
Daten sind bereitgestellt durch das CVE Programm von einer CVE Numbering Authority (CNA) (Unstrukturiert).
