TillKit < 1.0.5 - Unauthenticated POS Takeover via Hard-Coded Default Manager PIN
The TillKit WordPress plugin before 1.0.5 does not require the hard-coded, publicly known PIN of the privileged POS account it creates on activation to be changed before use, and it authenticates its public POS login endpoint on that PIN alone with no identity or capability check, allowing unauthenticated attackers to obtain a privileged POS session and thereby read customer and site-user personal data and modify store data.

CWE-287 02/10/2026
JSON API Auth <= 3.1.2 - Unauthenticated Authentication Bypass via Cached 'generate_auth_cookie' Response
The JSON API Auth plugin for WordPress is vulnerable to Authentication Bypass via Cached Session Cookie Disclosure in all versions up to, and including, 3.1.2. The vulnerability exists because the required PI-Media/json-api parent plugin caches controller dispatch results in transients keyed solely by URI and query string, ignoring HTTP method and POST body; this causes the `generate_auth_cookie()` endpoint — which embeds a live WordPress `logged_in` cookie produced by `wp_generate_auth_cookie()` directly in its JSON response body — to serve that cached authenticated response to any subsequent unauthenticated GET request to the same URI. This makes it possible for unauthenticated attackers to retrieve a valid Administrator `logged_in` session cookie from the cached response and use it to fully authenticate as the site Administrator, including via the same plugin's `get_currentuserinfo` endpoint and any cookie-authenticated controller action. Exploitation requires the PI-Media/json-api parent plugin to be installed and active with the Auth controller enabled, and a legitimate Administrator must have POSTed to `/api/auth/generate_auth_cookie/` within the preceding 24-hour cache TTL; the nominal HTTPS enforcement gate present in `Auth.php` is trivially bypassed by supplying `insecure=cool` as a request parameter.

Paytm Payment Gateway < 2.8.9 - Unauthenticated Order Status Manipulation via Payment Callback
The Paytm Payment Gateway WordPress plugin before 2.8.9 does not verify that payment callbacks genuinely originate from the payment provider when its secret key has not been configured, which is its state immediately after activation, allowing unauthenticated attackers to change the status of arbitrary orders, including marking unpaid orders as paid and reducing stock.

CWE-287 02/10/2026
Divi Membership <= 2.3.0 - Unauthenticated Authentication Bypass via 'paypal_param' Parameter
The Divi Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.0. The `process_paypal_callback` function, hooked to the `init` action, accepts a base64-encoded `paypal_param` GET parameter with no IPN validation, no cryptographic signature check, no ownership verification, and no nonce, allowing it to trust an entirely attacker-controlled user ID value that is passed directly to `wp_set_current_user()` and `wp_set_auth_cookie()`. This makes it possible for unauthenticated attackers to log in as any existing WordPress user — including administrators — by supplying an arbitrary user ID in the `paypal_param` GET parameter, resulting in full site takeover. The vulnerability is further compounded by the fact that the PayPal gateway class is instantiated unconditionally regardless of whether PayPal is enabled or configured, ensuring the vulnerable hook is always registered on every front-end request.

CWE-287 02/10/2026
DevKit Pro <= 2.3.0 - Unauthenticated Authentication Bypass to Administrator Account Takeover via 'original_user_id' Cookie in Frontend Revert Switch Flow
The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the `revert_switch` handler trusting the attacker-controlled `original_user_id` cookie as the privileged identity: `verify_nonce_and_capability()` incorrectly checks the `manage_options` capability on the user identified by the cookie rather than on the actual requester via `current_user_can()`, while the switch-back form and a valid session-bound nonce are emitted publicly via `wp_footer` to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.

Unauthenticated Remote Code Execution via MacTool Command Injection in TP-Link Tapo C120 & C200
Tapo C120 v1 and C200 V5
do not adequately protect login challenge data or sanitize
attacker-controlled input processed by the MacTool handler. An unauthenticated
attacker on the same local network can replay login challenge data to obtain an
administrative session, enable a privileged service that becomes accessible
after a reboot, and submit crafted input to execute arbitrary commands within
the device management process.
Successful
exploitation may allow arbitrary command execution on the camera and compromise
the confidentiality, integrity, and availability of the affected device.
Exploitation requires access from the same local network, replay of the login
challenge data, activation of the privileged service, and a device reboot.

Fleet before 4.87.0 Authentication Bypass via Device Identifiers
Fleet versions before 4.87.0 contain an authentication bypass vulnerability in the device API that accepts hostnames and hardware serials as authentication tokens in addition to device UUIDs. Unauthenticated attackers who know or guess these non-secret identifiers can authenticate as iOS/iPadOS hosts to read device data and trigger device-scoped actions including software installation and MDM migration.

Ultimate Multisite <= 2.15.0 - Unauthenticated Authentication Bypass via 'checkout_form' Parameter
The Ultimate Multisite – WordPress Multisite SaaS & WaaS Platform plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.15.0 via the `checkout_form` parameter of the `login_customer_after_checkout` function. This is due to the publicly accessible `wu_ajax_nopriv_wu_validate_form` AJAX handler accepting a freely obtainable checkout nonce, and the `checkout_form=wu-finish-checkout` parameter causing `get_validation_rules()` to discard all validation rules while `finish_checkout_form_fields()` returns an empty step list — forcing `is_last_step()` to return true and routing the request directly into full order processing — after which `maybe_create_customer()` resolves the attacker-supplied `email_address` to an existing WordPress user ID without any authentication or ownership verification, and `login_customer_after_checkout()` calls `wp_set_auth_cookie()` for that user ID via a passwordless code path. This makes it possible for unauthenticated attackers to log in as any existing WordPress user — including a Network Super Admin — simply by knowing their email address. Exploitation requires that the targeted user account has no pre-existing Ultimate Multisite customer record; accounts such as a Network Super Admin on a fresh Multisite install, or any administrator or editor added before Ultimate Multisite was configured, satisfy this condition and are therefore exploitable.

CWE-287 01/10/2026
MISP HOTP Token Replay via Stale Session-Cached Counter Allows Second-Factor Authentication Bypass
MISP contains a vulnerability in its one-time password (OTP) authentication flow that allows replay of a consumed HOTP (paper) token and rewinding of the token counter.
The HOTP verification logic compared the submitted token against a counter value that was cached in the user's session at the time the password was entered, rather than against the authoritative counter stored in the database. Because the session-cached counter is not updated after a token is successfully consumed, an attacker who holds a valid session (password already submitted) can reuse a previously burned HOTP token. The stale cached counter still matches the replayed token, granting a second successful authentication and effectively rewinding the counter state.
Preconditions:
- The target user has HOTP (paper token) second-factor authentication enabled.
- The attacker possesses a valid session in which the password step has already been completed (the OTP step is pending).
- The attacker has access to at least one HOTP token value (e.g., a paper token list).
Security impact:
- Bypass of the second authentication factor, allowing unauthorized access to a user's MISP account.
- Corruption of the HOTP counter state, potentially invalidating subsequent legitimate tokens or enabling further replays.
Affected versions: <2.5.48.

Kiteworks Email Protection Gateway improper authentication
Improper authentication in a Kiteworks Email Protection Gateway administrative service. An administrative service in Kiteworks Email Protection Gateway did not consistently enforce administrator authentication, so the required password check could be bypassed. An attacker who referenced a valid administrator account could potentially create, modify, or delete internal users and managed domains and change their security-feature configuration without authenticating; deleting a managed domain also removes its user accounts and could lock administrators out of the gateway.
