Vulnerability from github – Published: 2019-12-26 17:58 – Updated: 2022-06-06 17:16Versions 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.
