Name of the Vulnerable Software and Affected Versions GreenBrowser versions prior to 1.2

Description The issue arises when apps rely on URL Parsing to verify that a given URL points to a trusted server. However, there are multiple ways to get URL parsing and verification wrong, allowing an attacker to circumvent access control.

Recommendations For GreenBrowser versions prior to 1.2, update to version 1.2 to resolve the issue. As a temporary workaround, consider restricting access to sensitive areas of the application that rely on URL parsing for access control until the update can be applied.
