Summary
OneUptime to rozwiązanie do monitorowania i zarządzania usługami online. W wersjach przed 10.0.21, użytkownik o niskich uprawnieniach może obejść autoryzację i izolację najemców w OneUptime v10.0.20 i wcześniejszych, wysyłając sfałszowany nagłówek is-multi-tenant-query wraz z kontrolowanym nagłówkiem projectid.
Risk Assessment
Atakujący mogą uzyskać dostęp do danych projektów należących do innych najemców, co prowadzi do ujawnienia danych oraz pełnego przejęcia konta ofiary. To stwarza poważne ryzyko dla bezpieczeństwa danych w organizacji.
Recommendation
Zaleca się aktualizację do wersji 10.0.21, aby usunąć tę podatność oraz wprowadzenie dodatkowych kontroli bezpieczeństwa w celu ochrony przed podobnymi atakami.

- CVE-2026-123966Critical
A vulnerability was found in Tenda AC19 version 16.03.10.07 in the saveParentControlInfo function of the /goform/saveParentControlInfo file. Manipulating the deviceId argument causes a heap-based buffer overflow. The attack can be carried out remotely, and the exploit has been publicly disclosed.
- CVE-2026-120984Critical
A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during setup. An authenticated attacker with client management permissions can bypass security controls and upload a malicious JavaScript policy that executes on the server.
- 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.
- CVE-2026-123961Critical
A vulnerability was detected in TOTOLINK CA300-PoE version 6.2c.884 affecting the setWiFiBasicConfig function in /cgi-bin/cstecgi.cgi. Manipulation of the KeyStr argument leads to a buffer overflow. The attack can be initiated remotely and a public exploit is available.
- CVE-2026-123960Critical
In TOTOLINK CA300-PoE version 6.2c.884, the setWanConfig function in /cgi-bin/cstecgi.cgi improperly handles the pppoeUser/priDns/secDns arguments, leading to a buffer overflow. The vulnerability can be exploited remotely, and a public exploit is already available.
- CVE-2026-123959Critical
In TOTOLINK CA300-PoE version 6.2c.884, the setLanguageCfg function in /cgi-bin/cstecgi.cgi improperly processes the langType argument, resulting in a buffer overflow. The attack can be initiated remotely, and the exploit has been publicly released.
- CVE-2026-123958Critical
In TOTOLINK CA300-PoE version 6.2c.884, the setLanConfig function in /cgi-bin/cstecgi.cgi mishandles the lanDns/lanSecDns/langType arguments, leading to a buffer overflow. The vulnerability can be exploited remotely, and a public exploit is already available.
Original NVD description (English source)
OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, a low‑privileged user can bypass authorization and tenant isolation in OneUptime v10.0.20 and earlier by sending a forged is-multi-tenant-query header together with a controlled projectid header. Because the server trusts this client-supplied header, internal permission checks in BasePermission are skipped and tenant scoping is disabled. This allows attackers to access project data belonging to other tenants, read sensitive User fields via nested relations, leak plaintext resetPasswordToken, and reset the victim’s password and fully take over the account. This results in cross‑tenant data exposure and full account takeover. This vulnerability is fixed in 10.0.21.
