handlebars.java FileTemplateLoader Path Traversal
Impact
Any application that passes user-controlled input to Handlebars.compile() using a FileTemplateLoader (or ClassPathTemplateLoader) is vulnerable to arbitrary file read. This is a realistic attack surface for web applications that use template names from URL path parameters, request parameters, or other user-controlled sources.
Patches
com.github.jknack:handlebars:4.5.2
Workarounds
Validate template name is derived from user input.

Связанные уязвимости
Handlebars.java provides logic-less and semantic Mustache templates with Java. Prior to 4.5.2, applications that pass user-controlled input to Handlebars.compile() using FileTemplateLoader or ClassPathTemplateLoader are vulnerable to path traversal, allowing arbitrary file read through template names derived from URL path parameters, request parameters, or other user-controlled sources. This issue is fixed in version 4.5.2.
