CVE-2026-31027
CriticalSummary
TOTOlink A3600R w wersji v5.9c.4959 zawiera podatność na przepełnienie bufora w interfejsie setAppEasyWizardConfig w pliku /lib/cste_modules/app.so. Problem wynika z niewłaściwej walidacji długości parametru rootSsid, co pozwala zdalnym atakującym na wywołanie przepełnienia bufora, co może prowadzić do wykonania dowolnego kodu lub odmowy usługi.
Risk Assessment
Podatność ta stwarza ryzyko dla organizacji, umożliwiając zdalnym atakującym potencjalne przejęcie kontroli nad urządzeniem lub zakłócenie jego działania. Może to prowadzić do poważnych konsekwencji, w tym utraty danych lub przerwy w świadczeniu usług.
Recommendation
Zaleca się aktualizację oprogramowania urządzenia do najnowszej wersji, która eliminuje tę podatność. Dodatkowo, warto wdrożyć mechanizmy monitorowania i zabezpieczeń, aby zminimalizować ryzyko ataków zdalnych.

- CVE-2026-122041Critical
The Checkout Field Editor for WooCommerce (Pro) plugin for WordPress up to and including 3.8.0 is vulnerable to unauthorized deletion of arbitrary attachments due to a missing capability/ownership check in the ajax_remove_uploaded() function. The handler is registered for both wp_ajax and wp_ajax_nopriv and gated solely by the 'file_handling_nonce' nonce, which is exposed in the public checkout page markup.
- CVE-2026-119075Critical
The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in FormHandler::validate_checkout_fields() in versions up to and including 1.1.4. The checkout registration path stores the raw $_POST['user_roles'] value without validation, and add_user_data() injects it as the new account's role.
- CVE-2026-118066Critical
The LatePoint plugin for WordPress is vulnerable to authentication bypass via account takeover in versions up to and including 5.7.6. OsModel::build_conditions_query() compares WHERE-clause values against literal strings 'IS NULL' and 'IS NOT NULL' and concatenates a match directly into SQL without binding, allowing unauthenticated attackers to send params[password_reset_token]=IS NOT NULL to the public customer_cabinet__change_password AJAX route and overwrite the lowest-id customer's password.
- CVE-2026-104014Critical
The Naimur Email OTP Verification for WooCommerce plugin is vulnerable to authentication bypass in versions up to and including 2.1.0. The password-reset finalization endpoint authorizes the reset solely by the presence of a database row marking an email as 'VERIFIED', with no timestamp check, session binding, or per-reset token, and the scheduled cleanup cron has no handler so it never runs.
