A fix is referenced (a reference tagged "Patch", often a source commit), but no release containing it is confirmed — find the release that contains it; until it is applied, mitigate (WAF / firewall / segmentation).
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.
CISA SSVCTrack at low or medium mission impact; Track* at high (mission-essential systems).
A fix is referenced, but no release containing it is confirmed. Check the referenced fix and the vendor's advisory for a release that contains it and apply that within your standard update timelines; until then, restrict network exposure of the affected system or apply the vendor's mitigation.
Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
