What is CVE-2019-10909?
A cross-site scripting (XSS) vulnerability exists in the Symfony Framework where validation messages are not properly escaped. This flaw can be exploited when user input is displayed in web applications, leading to potential injection of malicious scripts. Affected versions include Symfony 2.7 before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, and earlier versions of 4.x before 4.1.12 and 4.2.x before 4.2.7. It is crucial for developers to upgrade their Symfony installations to mitigate this risk.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
