🚨 In Jenkins Email Extension Plugin 2.93 and earlier, attackers can easily bypass Script Security, unleashing arbitrary code in your Jenkins controller! 🔥 Think of it like a restaurant where the kitchen staff can add secret ingredients without any checks — one rogue chef could turn a simple recipe into a dish that’s toxic! This vulnerability allows an attacker to execute any code they want in the context of your Jenkins instance. The consequences could be absolutely devastating: unauthorized access, data breaches, or even complete control over your CI/CD pipeline. Protecting your build environment is critical!
Think of it like a restaurant where the kitchen staff can add secret ingredients without any checks — one rogue chef could turn a simple recipe into a dish that’s toxic! This flaw stems from email templates defined in folders not being subjected to Script Security protection, allowing attackers to exploit this oversight and run malicious code within your Jenkins controller JVM.
