Linux Distros Unpatched Vulnerability : CVE-2026-106445

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Handlebars provides the power necessary to let users build semantic templates. From 3.0.0 until 4.7.10, Handlebars lookupProperty returns...

Server-Side Template Injection

Handlebars is vulnerable to Server-Side Template Injection SSTI. The vulnerability is due to improper enforcement of prototype-access restrictions in lookupProperty, which allows an attacker to bypass the deny list, access the Function constructor through a controlled template, and execute...

GHSA-P8WG-VRV2-V86F Handlebars: JavaScript Injection via Own Property Check Bypass

Summary Handlebars can expose the Function constructor despite its prototype-access deny list. When a template reaches Function.prototype, its own constructor property is returned before the deny list is checked. An attacker who can render a controlled template with allowProtoMethodsByDefault: tr...
