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.

GHSA-r4gv-qr8j-p3pg — handlebars.java FileTemplateLoader Path Traversal

2026-10-06T09:02:35.771068+00:00

Affected: Maven: com.github.jknack:handlebars

### 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.

```java if (!file.getPath().startsWith(new File(prefix).getCanonicalPath())) { throw new IOException("Path traversal attempt detected: " + location); } ```
