Prevent XXE Injection in Symfony Framework
XML External Entity (XXE) Injection is a critical vulnerability that can lead to data disclosure, server-side request forgery (SSRF), or remote code execution. In modern PHP applications using the Symfony framework, this vulnerability can arise when parsing XML input improperly. In this post, we’ll explore how XXE injection works, how it affects Symfony applications, how to test for it using our Website Vulnerability Scanner online free, and how to mitigate it. You’ll also find code examples that simulate real-world vulnerabilities and fixes.
