CVE-2026-90542

WWBN AVideo Missing Authorization via remindMe.json.php

Published Sep 12, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate that logged-in users can access live schedules before creating reminders via remindMe.json.php. Authenticated attackers can create scheduler reminders for private live schedules they cannot view and learn the private schedule title from the generated email job.

Analysis

Technical impact

WWBN AVideo has a missing authorization check in the remindMe.json.php endpoint. Authenticated users that otherwise cannot access the content can still create scheduler reminders. The generated email job contains the schedule title, allowing the attacker to discover the title of a private schedule. This flaw is a classic missing authorization weakness (CWE-639).

Affected Systems

The vulnerability exists in WWBN AVideo releases that include commit c3edcc274c389816d434acadac07ee Any release built from that commit onward is potentially vulnerable until the authorization check is restored.

Risk and Exploitability

The CVSS score is 5.3, and the vulnerability is not listed in the CISA KEV catalog. The EPSS score is less than 1%. Once authenticated, exploitation is trivial: an attacker can freely create reminders for private schedules and learn the schedule title from the email job.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
