Vulnerability in wwbn/avideo (CVE-2026-43875)
Summary
Vulnerability in wwbn/avideo (CVE-2026-43875). Confidential information can be exposed externally. Exploitable via GET /plugin/MobileManager/oauth2.php.
Original description
The description as published by the source.
Summary
plugin/MobileManager/oauth2.php completes an OAuth login by sending an HTTP 302 Location: oauth2Success.php?user=&pass= where `` is the victim's stored password hash (md5(hash("whirlpool", sha1(password)))) read directly from the users table. AVideo's own login endpoint (objects/login.json.php) accepts an encodedPass=1 flag that bypasses hashing and performs a direct string comparison between the supplied value and the stored hash. Anyone who captures the redirect URL — via server logs, referrer leakage, or browser history — therefore obtains a credential equivalent to the plaintext password and can fully take over the account, including admin accounts.
Details
Sink: hash inlined in a GET redirect
plugin/MobileManager/oauth2.php:98-102:
$pass = rand();
$users_id = User::createUserIfNotExists($user, $pass, $name, $email, $photoURL);
$adapter->disconnect();
$userObject = new User($users_id);
header("Location: oauth2Success.php?user=" . $userObject->getUser() . "&pass=" . $userObject->getPassword());
$userObject->getPassword() returns the raw database column (objects/user.php:159-162):
public function getPassword()
{
return strip_tags($this->password);
}
The returned value is the stored password hash for the account (existing or freshly-created). It is transported to the browser as a query-string parameter in the Location: header, so it is written to:
