Summary

Prototype Pollution in handlebars

Description

Versions of handlebars prior to 3.0.8 or 4.3.0 are vulnerable to Prototype Pollution leading to Remote Code Execution. Templates may alter an Objects' __proto__ and __defineGetter__ properties, which may allow an attacker to execute arbitrary code through crafted payloads.

Recommendation

Upgrade to version 3.0.8, 4.3.0 or later.
