EchelonGraph scoreLOW confidence

This high-severity CVE scores 7.5 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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. 

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