Description

Vvveb before version 1.0.8.2 contains an information disclosure vulnerability that allows unauthenticated attackers to obtain sensitive server information by triggering unhandled exceptions in the password-reset module. Attackers can access the admin password-reset endpoint to trigger a fatal error caused by a missing namespace import, which exposes the absolute server file path, internal class namespaces, line numbers, and source code excerpts through the debug exception handler rendered to unauthenticated requests.
