Summary

A path traversal vulnerability in Handlebars.java allows arbitrary file read. Applications passing user-controlled input to Handlebars.compile() with FileTemplateLoader or ClassPathTemplateLoader are affected.

Risk Assessment

An attacker can read sensitive system or configuration files, leading to data leakage and potential compromise of the application.

Recommendation

Upgrade Handlebars.java to version 4.5.2 or later. Additionally, validate and sanitize user input used as template names.

Other vulnerabilities in Handlebars.java

CVE-2026-63490High
Handlebars.java before version 4.5.3 contains a file read vulnerability. SpringTemplateLoader does not properly validate view names, allowing a remote attacker to read files accessible to the JVM when an application exposes a controller with a user-influenced view name. Fixed in version 4.5.3.

Original NVD description (English source)

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.
