CVE-2026-41931Public exploitNetwork attack vector

Unauthenticated server disclosure via debug exception renderer

Published May 6, 2026 · Updated May 6, 2026

Information disclosure in givanz Vvveb before 1.0.8.2 allows remote attackers to obtain sensitive server details without authentication. The password-reset controller calls Locale without importing its namespace, causing an exception before the authentication gate; the default debug handler returns the absolute path, internal namespace, line number, and source excerpt. Anonymous network access to the admin reset endpoint is sufficient, and the disclosed data is limited to server and application internals rather than stored user data.
