Echo: handlebars: security update to 4.7.10

critical Tenable Cloud Security Plugin ID 474008

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Handlebars provides the power necessary to let users build semantic templates. From 4.0.0 until 4.7.10,
 Handlebars.compile() and Handlebars.precompile() accept pre-parsed AST objects while validating only
 selected PathExpression, NumberLiteral, and BooleanLiteral values. This issue bypasses the AST validation
 introduced in version 4.7.9 for CVE-2026-33937. An attacker who can supply an object instead of a template
 string can place JavaScript expressions in unchecked values such as Program.blockParams.length, a non-
 PathExpression parameter depth, a non-string StringLiteral.value, or a non-string PathExpression.original.
 The compiler emits those values into generated JavaScript, causing code execution in the server process
 when compile output renders or wherever precompile output is loaded. Applications that pass only template
 strings are not affected. This issue is fixed in version 4.7.10. (CVE-2026-106446)

Solution

Update the handlebars library and its related packages to version 4.7.10 or later.
