SCA: security update for org.freemarker:freemarker (GHSA-27j2-h3m2-8237)

critical Tenable Cloud Security Plugin ID 448371

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Path traversal vulnerability in Apache FreeMarker template loading mechanism, if the attacker can specify
 an arbitrary malformed locale identifier to FreeMarker, and the localized lookup configuration setting is
 enabled (it's by default enabled). This issue affects Apache FreeMarker from 2.2.0 through 2.3.34. Users
 are recommended to upgrade to version 2.3.35. Disabling localized lookup in previous versions also
 mitigates this. Note that even in versions affected by this vulnerability, the files that can be loaded
 remain restricted by the TemplateLoader that FreeMarker is configured to use. In particular,
 FileTemplateLoader prevents attempts to traverse outside the baseDir specified in its constructor. Other
 TemplateLoader implementations may allow access outside their designated base directory, but they are
 still constrained by the underlying storage mechanism—for example, a loader wrapping a Java class loader
 can only access resources that the class loader can load, while one wrapping a web application context can
 only access resources available through that context. (CVE-2026-84939)

Solution

Update the org.freemarker:freemarker library and its related packages to version 2.3.35 or later.
