Overview
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements Used in a Template Engine in the join filter compilation process. An attacker can execute arbitrary PHP code by injecting malicious input into template arguments, which are incorporated into the generated PHP without proper escaping or validation. This allows code execution in the web-server process when the compiled template is rendered. This is only exploitable if the application compiles Volt templates that include attacker-controlled input.
