Technical description

n8n before 2.32.1 (and before 2.31.5) is vulnerable to account takeover via the Token Exchange Embed Login feature. When a validly-signed incoming token was matched to a local account by its email claim, the service did not verify that the email claim was verified, nor that the trusted key's permitted role ceiling covered that account. As a result, anyone able to obtain a token accepted by a configured trusted key (for example, a trusted issuer emitting unverified email addresses) could authenticate as any existing user and gain full account control. This issue only affects instances where the embed login feature is enabled and at least one trusted key source is configured.

——6A flaw has been found in macrozheng mall 0504e86. This vulnerability affects unknown code of the file /sso/getAuthCode of the component mall-portal Module. Executing a manipulation can lead to weak password recovery. The attack may be launched remotely. This attack is characterized by high complexity. It is stated that the exploitability is difficult. The exploit has been published and may be used. The vendor deleted the GitHub issue for this vulnerability without any explanation. Afterwards the vendor was contacted early about this disclosure via email but did not respond in any way.8h CVE-2026-143649.8 CRI

——6The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to account takeover via improper password reset validation in all versions up to, and including, 1.2.3. This is due to the plugin not properly validating a user's identity before resetting their password. This makes it possible for unauthenticated attackers to reset the password of arbitrary user accounts, including administrators, and gain access to those accounts.8h CVE-2026-92739.3 CRI

——6The Membership Plugin – Kadence Memberships plugin for WordPress (formerly Restrict Content) is vulnerable to password reset link poisoning leading to account takeover in all versions up to, and including, 4.0.0. This is due to the legacy lost-password handler rc_process_lost_password_form() consuming the attacker-controlled rc_redirect POST parameter into two unvalidated sinks in legacy/includes/forms.php: wp_redirect( esc_url( $_POST['rc_redirect'] ) . ... ) at line 243, and add_query_arg( array( 'key' => $key, 'login' => ... ), $_POST['rc_redirect'] ) inside rc_send_password_reset_email() at line 306. The nonce required to reach the handler is broadcast by the public [login_form] shortcode at line 207 to any anonymous visitor. This makes it possible for unauthenticated attackers to issue a password-reset request for any account (including administrators) whose reset email body points the victim at an attacker-controlled host carrying a valid reset key/login. When the victim clicks the link, the reset key leaks to the attacker, who can replay it against the legitimate site to complete account takeover.8h CVE-2026-18363—

——7A logic vulnerability in the password reset token validation routine implemented by osTicket in versions prior to v1.17.8 and v1.18.4. During the password reset process, the application retrieves the timestamp associated with the provided token and checks whether the configured validity period has expired. Consequently, the expiry check is only performed if the timestamp lookup fails, allowing tokens with an existing timestamp to bypass the intended expiry validation. Therefore, an attacker able to obtain a valid password reset token could reuse it to perform an unauthorised password reset and compromise the affected account.14d CVE-2026-646355.3 MED

——3Improper handling of the returnUrl parameter in the Forgot Password function of Veeam Service Provider Console allows an unauthenticated attacker to control the domain of the generated password reset link. When the targeted user clicks the link delivered by email, the reset code is transmitted to an attacker-controlled host, allowing the attacker to take over the account.14d
