CVE-2025-14510 2026-01-16 N/A 8.1 HIGH
Incorrect Implementation of Authentication Algorithm vulnerability in ABB ABB Ability OPTIMAX.This issue affects ABB Ability OPTIMAX: 6.1, 6.2, from 6.3.0 before 6.3.1-251120, from 6.4.0 before 6.4.1-251120.
CVE-2025-63210 1 Newtec 4 Celoxa504, Celoxa504 Firmware, Celoxa820 and 1 more 2026-01-15 N/A 9.8 CRITICAL
The Newtec Celox UHD (models: CELOXA504, CELOXA820) running firmware version celox-21.6.13 is vulnerable to an authentication bypass. An attacker can exploit this issue by modifying intercepted responses from the /celoxservice endpoint. By injecting a forged response body during the loginWithUserName flow, the attacker can gain Superuser or Operator access without providing valid credentials.
CVE-2025-4676 2026-01-08 N/A 8.8 HIGH
Incorrect Implementation of Authentication Algorithm vulnerability in ABB WebPro SNMP Card PowerValue, ABB WebPro SNMP Card PowerValue UL.This issue affects WebPro SNMP Card PowerValue: through 1.1.8.K; WebPro SNMP Card PowerValue UL: through 1.1.8.K.
CVE-2025-14273 1 Mattermost 1 Mattermost Server 2025-12-29 N/A 7.2 HIGH
Mattermost versions 11.1.x <= 11.1.0, 11.0.x <= 11.0.5, 10.12.x <= 10.12.3, 10.11.x <= 10.11.7 with the Jira plugin enabled and Mattermost Jira plugin versions <=4.4.0 fail to enforce authentication and issue-key path restrictions in the Jira plugin, which allows an unauthenticated attacker who knows a valid user ID to issue authenticated GET and POST requests to the Jira server via crafted plugin payloads that spoof the user ID and inject arbitrary issue key paths. Mattermost Advisory ID: MMSA-2025-00555
CVE-2025-13390 1 Wpdirectorykit 1 Wp Directory Kit 2025-12-16 N/A 10.0 CRITICAL
The WP Directory Kit plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.4.4 due to incorrect implementation of the authentication algorithm in the "wdk_generate_auto_login_link" function. This is due to the feature using a cryptographically weak token generation mechanism. This makes it possible for unauthenticated attackers to gain administrative access and achieve full site takeover via the auto-login endpoint with a predictable token.
CVE-2025-66489 2025-12-04 N/A N/A
Cal.com is open-source scheduling software. Prior to 5.9.8, A flaw in the login credentials provider allows an attacker to bypass password verification when a TOTP code is provided, potentially gaining unauthorized access to user accounts. This issue exists due to problematic conditional logic in the authentication flow. This vulnerability is fixed in 5.9.8.
CVE-2025-12419 1 Mattermost 1 Mattermost Server 2025-12-03 N/A 9.9 CRITICAL
Mattermost versions 10.12.x <= 10.12.1, 10.11.x <= 10.11.4, 10.5.x <= 10.5.12, 11.0.x <= 11.0.3 fail to properly validate OAuth state tokens during OpenID Connect authentication which allows an authenticated attacker with team creation privileges to take over a user account via manipulation of authentication data during the OAuth completion flow. This requires email verification to be disabled (default: disabled), OAuth/OpenID Connect to be enabled, and the attacker to control two users in the SSO system with one of them never having logged into Mattermost.
CVE-2025-12421 1 Mattermost 1 Mattermost Server 2025-12-03 N/A 9.9 CRITICAL
Mattermost versions 11.0.x <= 11.0.2, 10.12.x <= 10.12.1, 10.11.x <= 10.11.4, 10.5.x <= 10.5.12 fail to to verify that the token used during the code exchange originates from the same authentication flow, which allows an authenticated user to perform account takeover via a specially crafted email address used when switching authentication methods and sending a request to the /users/login/sso/code-exchange endpoint. The vulnerability requires ExperimentalEnableAuthenticationTransfer to be enabled (default: enabled) and RequireEmailVerification to be disabled (default: disabled).
CVE-2024-10127 1 M-files 1 M-files Server 2025-10-29 N/A 9.8 CRITICAL
Authentication bypass condition in LDAP authentication in M-Files server versions before 24.11 supported usage of OpenLDAP configurations that allowed user authentication without a password when the LDAP server itself had the vulnerable configuration.
CVE-2023-29357 1 Microsoft 1 Sharepoint Server 2025-10-28 N/A 9.8 CRITICAL
Microsoft SharePoint Server Elevation of Privilege Vulnerability
CVE-2025-53782 1 Microsoft 1 Exchange Server 2025-10-27 N/A 8.4 HIGH
Incorrect implementation of authentication algorithm in Microsoft Exchange Server allows an unauthorized attacker to elevate privileges locally.
CVE-2024-7593 1 Ivanti 1 Virtual Traffic Management 2025-10-24 N/A 9.8 CRITICAL
Incorrect implementation of an authentication algorithm in Ivanti vTM other than versions 22.2R1 or 22.7R2 allows a remote unauthenticated attacker to bypass authentication of the admin panel.
CVE-2025-61783 2025-10-15 N/A N/A
Python Social Auth is a social authentication/registration mechanism. In versions prior to 5.6.0, upon authentication, the user could be associated by e-mail even if the `associate_by_email` pipeline was not included. This could lead to account compromise when a third-party authentication service does not validate provided e-mail addresses or doesn't require unique e-mail addresses. Version 5.6.0 contains a patch. As a workaround, review the authentication service policy on e-mail addresses; many will not allow exploiting this vulnerability.
CVE-2025-3230 1 Mattermost 1 Mattermost Server 2025-10-15 N/A 5.4 MEDIUM
Mattermost versions 10.7.x <= 10.7.0, 10.6.x <= 10.6.2, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fails to properly invalidate personal access tokens upon user deactivation, allowing deactivated users to maintain full system access by exploiting access token validation flaws via continued usage of previously issued tokens.
CVE-2025-2571 1 Mattermost 1 Mattermost Server 2025-10-15 N/A 4.2 MEDIUM
Mattermost versions 10.7.x <= 10.7.0, 10.6.x <= 10.6.2, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fail to clear Google OAuth credentials when converting user accounts to bot accounts, allowing attackers to gain unauthorized access to bot accounts via the Google OAuth signup flow.
CVE-2025-43727 1 Dell 1 Data Domain Operating System 2025-10-14 N/A 7.5 HIGH
Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 7.7.1.0 through 8.1.0.10, LTS2024 release Versions 7.13.1.0 through 7.13.1.25, LTS 2023 release versions 7.10.1.0 through 7.10.1.50, contain an incorrect Implementation of Authentication Algorithm vulnerability in the RestAPI. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.
CVE-2025-2475 1 Mattermost 1 Mattermost Server 2025-10-02 N/A 5.4 MEDIUM
Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to invalidate the cache when a user account is converted to a bot which allows an attacker to login to the bot exactly one time via normal credentials.
CVE-2025-57808 1 Esphome 1 Esphome Firmware 2025-09-10 N/A 8.1 HIGH
ESPHome is a system to control microcontrollers remotely through Home Automation systems. In version 2025.8.0 in the ESP-IDF platform, ESPHome's web_server authentication check can pass incorrectly when the client-supplied base64-encoded Authorization value is empty or is a substring of the correct value. This allows access to web_server functionality (including OTA, if enabled) without knowing any information about the correct username or password. This issue has been patched in version 2025.8.1.
CVE-2024-5658 1 Born05 1 Two-factor Authentication 2025-09-03 N/A 4.8 MEDIUM
The CraftCMS plugin Two-Factor Authentication through 3.3.3 allows reuse of TOTP tokens multiple times within the validity period.
CVE-2024-4332 2025-08-29 N/A N/A
An authentication bypass vulnerability has been identified in the REST and SOAP API components of Tripwire Enterprise (TE) 9.1.0 when TE is configured to use LDAP/Active Directory SAML authentication and its optional "Auto-synchronize LDAP Users, Roles, and Groups" feature is enabled. This vulnerability allows unauthenticated attackers to bypass authentication if a valid username is known. Exploitation of this vulnerability could allow remote attackers to gain privileged access to the APIs and lead to unauthorized information disclosure or modification.
