CVE-2017-14423Hig0.497.50.00Sep 13, 2017htdocs/parentalcontrols/bind.php on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) devices does not prevent unauthenticated nonce-guessing attacks, which makes it easier for remote attackers to change the DNS configuration via a series of requests.
CVE-2002-0628Hig0.497.50.02Jan 7, 2003The Telnet service for Polycom ViewStation before 7.2.4 does not restrict the number of failed login attempts, which makes it easier for remote attackers to guess usernames and passwords via a brute force attack.
CVE-1999-1152Hig0.497.50.01Jun 3, 1998Compaq/Microcom 6000 Access Integrator does not disconnect a client after a certain number of failed login attempts, which allows remote attackers to guess usernames or passwords via a brute force attack.
CVE-2026-33667Hig0.487.40.00Apr 15, 2026OpenProject is an open-source project management application. In versions prior to 17.3.0, 2FA OTP verification in the confirm_otp action of the two_factor_authentication module has no rate limiting, lockout mechanism, or failed-attempt tracking. The existing brute_force_block_after_failed_logins setting only counts password login failures and does not apply to the 2FA verification stage, and neither the fail_login nor stage_failure methods increment any counter, lock the account, or add any delay. With the default TOTP drift window of ±60 seconds allowing approximately 5 valid codes at any time, an attacker who knows a user's password can brute-force the 6-digit TOTP code at roughly 5-10 attempts per second with an expected completion time of approximately 11 hours. The same vulnerability applies to backup code verification. This effectively allows complete 2FA bypass for any account where the password is known. This issue has been fixed in version 17.3.0.
CVE-2025-66413Hig0.487.40.00Mar 10, 2026Git for Windows is the Windows port of Git. Prior to 2.53.0(2), it is possible to obtain a user's NTLM hash by tricking them into cloning from a malicious server. Since NTLM hashing is weak, it is possible for the attacker to brute-force the user's account name and password. This vulnerability is fixed in 2.53.0(2).
CVE-2025-14362Hig0.477.30.00Apr 21, 2026The login limit is not enforced on the SFTP service of Fortra's GoAnywhere MFT prior to 7.10.0 if the Web User attempting to be logged in to is configured to log in with an SSH Key, making the SSH key vulnerable to being guessed via Brute Force.
CVE-2025-10161Hig0.477.30.00Nov 11, 2025Improper Restriction of Excessive Authentication Attempts, Client-Side Enforcement of Server-Side Security, Reliance on Untrusted Inputs in a Security Decision vulnerability in Turkguven Software Technologies Inc. Perfektive allows Brute Force, Authentication Bypass, Functionality Bypass.This issue affects Perfektive: before Version: 12574 Build: 2701.
CVE-2025-0417Hig0.46—0.00Apr 1, 2025Lack of protection against brute force attacks in Valmet DNA visualization in DNA Operate. The possibility to make an arbitrary number of login attempts without any rate limit gives an attacker an increased chance of guessing passwords and then performing switching operations.
CVE-2025-11566Med0.45—0.00Nov 12, 2025CWE-307: Improper Restriction of Excessive Authentication Attempts vulnerability exists that would allow an attacker on the local network to gain access to the user account by performing an arbitrary number of authentication attempts with different credentials on the /REST/shutdownnow endpoint.
CVE-2025-1714Med0.45—0.00Mar 5, 2025Lack of Rate Limiting in Sign-up workflow in Perforce Gliffy prior to version 4.14.0-7 on Gliffy online allows attacker to enumerate valid user emails and potentially DOS the server
CVE-2025-31991Med0.446.80.00Apr 13, 2026Rate Limiting for attempting a user login is not being properly enforced, making HCL DevOps Velocity susceptible to brute-force attacks past the unsuccessful login attempt limit.  This vulnerability is fixed in 5.1.7.
CVE-2026-7255Med0.426.50.00May 12, 2026** UNSUPPORTED WHEN ASSIGNED ** An improper restriction of excessive authentication attempts vulnerability in the web management interface of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow an adjacent attacker on the LAN to brute-force the password and bypass authentication.
CVE-2026-7820Med0.426.50.00May 11, 2026Improper restriction of excessive authentication attempts (CWE-307) in pgAdmin 4. pgAdmin enforces MAX_LOGIN_ATTEMPTS only inside its custom /authenticate/login view. Flask-Security's default /login view, which is registered automatically by security.init_app() and is reachable on every server, never consulted the User.locked field: pgAdmin's User model relied on Flask-Security's UserMixin.is_locked() (which always returns 'not locked') and Flask-Login's is_active (which only checks the active column, not locked). An attacker who triggered an account lockout via /authenticate/login could therefore obtain a session by re-submitting valid credentials directly to /login, defeating the brute-force-protection control for accounts using the INTERNAL authentication source. The same bypass also means that login attempts via /login are never rate-limited, so an attacker can perform an unbounded online password-guessing attack against INTERNAL accounts regardless of MAX_LOGIN_ATTEMPTS. Fix overrides User.is_active and User.is_locked() so the locked column is enforced on every authentication path. LDAP, OAuth2, Kerberos, and Webserver users are not reachable by this bypass because they have no local password and are rejected by Flask-Security's LoginForm.validate before the locked check; the lockout itself is also internal-only (the /authenticate/login view filters by auth_source=INTERNAL). This issue affects pgAdmin 4: before 9.15.
CVE-2026-41893Hig0.427.50.00May 9, 2026Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.25.0, the HTTP login endpoints (POST /login and POST /signalk/v1/auth/login) are protected by express-rate-limit (default: 100 attempts per 10-minute window, configurable via HTTP_RATE_LIMITS). The WebSocket login path — sending {login: {username, password}} messages over an established WebSocket connection — calls app.securityStrategy.login() directly without any rate limiting. An attacker can bypass HTTP rate limiting entirely by opening a WebSocket connection and attempting unlimited password guesses at the speed bcrypt allows (~20 attempts/sec with 10 salt rounds). This issue has been patched in version 2.25.0.
CVE-2026-26206Med0.426.50.00Apr 29, 2026Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.0.0 to before version 4.14.4, Wazuh's server API brute-force protection for POST /security/user/authenticate can be bypassed by sending concurrent authentication requests. Although the configured threshold (max_login_attempts, default 50) is enforced correctly for sequential requests, a parallel burst allows significantly more failed login attempts to be processed before the IP block is applied. This enables an attacker to perform more password guesses than the configured policy intends (e.g., 100 attempts processed where 50 should be allowed). This issue has been patched in version 4.14.4.
CVE-2026-22616Med0.426.50.00Apr 16, 2026Eaton Intelligent Power Protector (IPP) software allows repeated authentication attempts against the web interface login page due to insufficient rate‑limiting controls. This security issue has been fixed in the latest version of Eaton IPP which is available on the Eaton download centre.
CVE-2026-25577Hig0.427.50.00Feb 10, 2026Emmett is a framework designed to simplify your development process. Prior to 1.3.11, the cookies property in mmett_core.http.wrappers.Request does not handle CookieError exceptions when parsing malformed Cookie headers. This allows unauthenticated attackers to trigger HTTP 500 errors and cause denial of service. This vulnerability is fixed in 1.3.11.
CVE-2025-10658Med0.426.50.01Sep 20, 2025The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.3.7. This is due to missing rate limiting on the OTP verification for guest login. This makes it possible for unauthenticated attackers to bypass authentication and gain unauthorized access to customer support tickets by brute forcing the 6-digit OTP code.
CVE-2025-53544Hig0.427.50.00Aug 5, 2025Trilium Notes is an open-source, cross-platform hierarchical note taking application with focus on building large personal knowledge bases. In versions below 0.97.0, a brute-force protection bypass in the initial sync seed retrieval endpoint allows unauthenticated attackers to guess the login password without triggering rate limiting. Trilium is a single-user app without a username requirement, and brute-force protection bypass makes exploitation much more feasible. Multiple features provided by Trilium (e.g. MFA, share notes, custom request handler) indicate that Trilium can be exposed to the internet. This is fixed in version 0.97.0.
CVE-2025-1496Med0.426.50.00Mar 20, 2025Improper Restriction of Excessive Authentication Attempts vulnerability in BG-TEK Coslat Hotspot allows Password Brute Forcing, Authentication Abuse.This issue affects Coslat Hotspot: before 6.26.0.R.20250227.
