CVE-2026-41931 — Vvveb security vulnerability

Medium CVSS 6.9

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.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
