Attackers can request codes using known mobile numbers or email addresses, read them from responses, and authenticate as victims via POST /sys/emailOrMobileLogin/login to hijack accounts.Show less

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when the "Automatic account link on initial logon" setting is enabled, Zammad binds an incoming third-party (SSO) identity to an existing local account by matching the email address the identity provider reports, without verifying that the provider actually confirmed ownership of that email. An attacker who controls any identity at a configured provider, including, by default, any Azure AD tenant via Zammad's multi-tenant Microsoft 365 /common app registration, can set that identity's email to a victim's address, authenticate, and be logged in as the victim. This bypasses the victim's local password entirely and affects any existing account, including agents and administrators. Zammad will honor the xms_edov ID token claim when email verification is required in the Microsoft 365 setting, treating a missing claim as unverified. This issue is fixed in version 7.1.2.Show less

Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary In Zammad's inbound PGP email processing, the return value of the gpg verification call was silently discarded. Regardless of whether gpg reported a valid, invalid, or missing signature, the handler unconditionally wrote sign: { success: true, comment: "Good signature" } to the article's security preferences. Impact Any sender could tamper with the body of a multipart/signed PGP email, or craft a message with an entirely fabricated or mismatched signature, and Zammad would display it to the recipient as cryptographically verified with a "Good signature" label. Users and agents relying on Zammad's signature indicator to confirm message authenticity and integrity would be misled into trusting modified or forged content. The vulnerability affects all inbound PGP-signed emails processed while the PGP integration is enabled. This issue is fixed in version 7.0.2.Show less

A vulnerability has been found in GibbonEdu Gibbon up to 30.0.01. The affected element is the function makeBlock of the file modules/Planner/units_add_blockAjax.php of the component Unit Planner. The manipulation of the argument gibbonUnitBlockID/mode leads to missing authentication. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 31.0.00 is sufficient to fix this issue. The identifier of the patch is 07e719368eae8dfb4e22e19424ceab6074164ebc. It is recommended to upgrade the affected component.Show less

Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections.Show less

ZITADEL is an open source identity management platform. From 4.0.0 until 4.16.1, ZITADEL Login V2 creates a browser session after password verification and can reuse that session for a later authentication request without verifying a user's enrolled TOTP, OTP, or U2F second factor. When the MFA step is abandoned and login starts again, session-validity checks require MFA only when the organization enables Force MFA or Force MFA for local users only, so a voluntarily enrolled factor can be skipped while completing an OIDC or SAML callback for a customer application. Login V1, the ZITADEL Console, Management and Admin APIs, and user self-management are not affected. This issue is fixed in version 4.16.1.Show less

Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the `vk-app` backend accepted VK application callback data without verifying the callback signature when the `auth_key` parameter was omitted. Applications using this backend could treat unsigned attacker-controlled data as a verified VK identity. An attacker could choose callback fields such as `viewer_id`, `access_token`, `api_id`, and `api_result`, potentially allowing authentication as an arbitrary VK user ID. The issue affects only applications using the `vk-app` backend. The issue has been fixed in version 5.0.0 by requiring `auth_key` to be present and valid before callback data is trusted.Show less

Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the SAML backend accepted SAML responses on the Assertion Consumer Service endpoint without verifying that they matched a previously issued `AuthnRequest`. Applications using SAML account association could allow an attacker with a valid account on a trusted IdP to link the attacker's SAML identity to a logged-in victim's local account. The attacker could then authenticate through SAML and gain access to the victim's account. The issue affects applications using the SAML backend together with authenticated account association. The issue has been fixed in version 5.0.0 by validating SAML responses against stored `AuthnRequest` IDs.Show less

authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an authentik SAML Source verifies an assertion's signature and validity period but does not ensure that the identity provider issued the assertion for that Source or in response to a login request from that Source. The SAML Source also does not record already accepted assertions, allowing replay. An unauthenticated actor who possesses such a valid assertion can use an assertion intended for another service provider or reuse an earlier assertion to authenticate as the user named by the assertion. Only SAML Sources are affected; SAML Providers and other Source types are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.Show less

authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, authentik email authenticator enrollment during an authentication or enrollment flow accepts a recipient address supplied in the setup request instead of using the address already established by the flow. An actor who knows a target user's password can substitute an attacker-controlled address, receive the one-time code, and finish enrolling the factor as the target. The target must not have enrolled the email factor already. Successful enrollment gives the actor a session as the target and access to single sign-on applications behind the account. Other authenticator types are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.Show less

The door access control on a Norwegian Cruise Line asset grants entry based only on the credential's static 7-byte UID stored on an NTAG212 NFC chip. A UID is a manufacturer serial number sent in the clear on every read and is not intended to be secret or to authenticate the holder. Validating on the UID of the NTAG212 NFC chip alone is identification, not authentication, and the credential has no challenge-response capability that would resist copying.Show less

phpMyFAQ is an open source FAQ web application. Versions 3.2.0 through 4.1.5 contain an authentication bypass in its public two-factor authentication verification flow: an unauthenticated attacker can submit an account’s numeric user ID and a valid or brute-forced six-digit TOTP code without first authenticating with the account password, allowing takeover of any 2FA-enabled account, including administrator accounts. Version 4.1.6 is patched by binding TOTP verification to a session established after successful password authentication and limiting failed TOTP attempts. No official workaround is documented; affected installations should upgrade to 4.1.6 or later.Show less

The EthPress – Web3 Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.5. This is due to the verify_login() function in app/Login.php containing a missing return statement in the signature verification failure branch — when Signature::verify2() reports a mismatch, the function only assigns a WP_Error to a local variable and continues executing, causing unconditional fall-through to the login block where Address::log_in() calls wp_set_auth_cookie() regardless of whether the submitted signature is valid. This makes it possible for unauthenticated attackers to log in as any WordPress user who has a linked wallet address — including administrators — by submitting that user's public wallet address alongside an arbitrary well-formed signature, enabling full site takeover.Show less
