Important Security Update: Addressing CVE-2024-33665 in Angular Translate

The popular JavaScript translation library for AngularJS 1.x apps, angular-translate, has recently been identified with a cross-site scripting (XSS) vulnerability – tagged as CVE-2024-33665, this security flaw presents significant risks, as it affects all versions from v2.4.0 onwards. Angular-translate is widely utilized for dynamic content translation across various applications, making this vulnerability particularly concerning.

The core of the issue lies in the unsanitized keys used by the translate directive, which do not sanitize input before it is rendered. This could allow attackers to inject malicious scripts into the application, potentially leading to unauthorized access to sensitive data or manipulation of user sessions.

Steps to Reproduce:

The vulnerability can be triggered by injecting malicious code into input fields that are then processed by the translate directive. A proof of concept demonstrating this exploit is available on StackBlitz, showing how malicious scripts can be introduced into a system using angular-translate.

Addressing the Issue:

Despite angular-translate for AngularJS reaching its end-of-life, HeroDevs has stepped up to provide a critical patch to address this vulnerability. This patch ensures that input keys are properly sanitized, thus blocking the potential for XSS attacks through this vector.
