CVE-2026-116238 2026-10-30 N/A 8.1 HIGH
In server mode pgAdmin 4 locks an internal account after MAX_LOGIN_ATTEMPTS failed logins (3 by default). The limit could be bypassed, giving an unauthenticated attacker an unlimited number of password guesses against any internal account, including the administrator's, in the default configuration: - Flask-Security registers its own views next to pgAdmin's. A login submitted to its /login view was checked and logged in without pgAdmin's failed login count or lock. Its /verify view checked a signed-in user's password without limit, its /change view changed a password without pgAdmin's change password permission or re-encrypting the user's saved server passwords, and its /reset views sent and applied password resets for accounts that are not internal or are locked. - The internal account was looked up by its exact username, while the login form matches the email ignoring case, so a login with the username typed in another case was neither counted nor checked for the lock. - With LDAP or webserver authentication also configured, a wrong internal password was never counted, and with Kerberos or webserver authentication configured a guess could be answered without being counted. In addition, where accounts from different authentication sources share an email address, a password reset could be sent for, or applied to, an account from another source, and the About box showed the server configuration to a user whose email was that of an administrator's account. The fix refuses submissions to Flask-Security's own views, counts every failed internal login however the username is typed and whatever other sources are configured, no longer lets a login that posts a password fall back to an authentication source that does not check it, and locks only internal authentication. Password resets and the About box act only on the user's own internal account. Desktop mode is not affected. This issue affects pgAdmin 4: before 9.19.
CVE-2026-22114 2026-10-30 N/A N/A
HTTP basic auth enforces no retry limit or backoff. Combined with the default service password, the keyspace is exhaustible.
CVE-2026-107256 2026-10-30 N/A N/A
Improper Restriction of Excessive Authentication Attempts vulnerability in Drupal Shield allows Brute Force. This issue affects Shield versions: from 0.0.0 to 1.9.0.
CVE-2026-111501 2026-10-30 N/A 5.4 MEDIUM
Dell OpenManage Enterprise, versions prior to 4.8.0, contains an Improper Restriction of Excessive Authentication Attempts vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Launch of phishing attacks.
CVE-2026-61611 2026-10-29 N/A 7.5 HIGH
Lychee is a free, open-source photo-management tool. Prior to 7.6.1, POST /api/v2/Album::unlock has no throttle, attempt counter, backoff, CAPTCHA, or lockout. UnlockAlbumRequest::authorize() permits any caller to submit attempts, and app/Actions/Album/Unlock.php verifies each guess with Hash::check without limiting repeated failures. A remote unauthenticated attacker who knows or can obtain an album identifier can automate password guesses against a password-protected album and, if the password is recovered, gain access to its private photo collection. This issue is fixed in version 7.6.1.
CVE-2023-54347 1 Open-emr 1 Openemr 2026-10-28 N/A 7.5 HIGH
OpenEMR 7.0.1 contains an authentication brute force vulnerability that allows attackers to bypass rate limiting protections by sending repeated login attempts to the main login endpoint. Attackers can submit POST requests with authUser and clearPass parameters to systematically test username and password combinations without account lockout restrictions.
CVE-2026-107145 2026-10-27 N/A N/A
The twofactor_gauthenticator plugin for Roundcube is vulnerable to brute-forcing of the second-factor code. Due to the lack of rate limiting, an attacker who obtains user's password can submit arbitrary 6-digit codes, resulting in second-factor bypass and unauthorized access to the system. This issue was fixed in commit 4640889.
CVE-2026-15586 2026-10-27 N/A 5.3 MEDIUM
Improper restriction of excessive authentication attempts vulnerability in İdvlabs Software and Consulting Services Inc. Ontime allows Brute Force. This issue affects Ontime: through 2026-10-27.  NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-60424 1 Nagios 1 Fusion 2026-10-27 N/A 7.6 HIGH
A lack of rate limiting in the OTP verification component of Nagios Fusion v2024R1.2 and v2024R2 allows attackers to bypass authentication via a bruteforce attack.
CVE-2026-33667 1 Openproject 1 Openproject 2026-10-26 N/A 7.4 HIGH
OpenProject 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-2026-40586 2026-10-26 N/A 7.5 HIGH
blueprintUE is a tool to help Unreal Engine developers. Prior to 4.2.0, the login form handler performs no throttling of any kind. Failed authentication attempts are processed at full network speed with no IP-based rate limiting, no per-account attempt counter, no temporary lockout, no progressive delay (Tarpit), and no CAPTCHA challenge. An attacker can submit an unlimited number of credential guesses. The password policy (10+ characters, mixed case, digit, special character) reduces the effective keyspace but does not prevent dictionary attacks, credential stuffing from breached databases, or targeted attacks against known users with predictable passwords. This vulnerability is fixed in 4.2.0.
CVE-2026-22616 1 Eaton 1 Intelligent Power Protector 2026-10-26 N/A 6.5 MEDIUM
Eaton 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-2026-33879 1 Aicentre 1 Federated Learning And Interoperability Platform 2026-10-26 N/A 9.8 CRITICAL
Federated Learning and Interoperability Platform (FLIP) is an open-source platform for federated training and evaluation of medical imaging AI models across healthcare institutions. The FLIP login page in versions 0.1.1 and prior has no rate limiting or CAPTCHA, enabling brute-force and credential-stuffing attacks. FLIP users are external to the organization, increasing credential reuse risk. As of time of publication, it is unclear if a patch is available.
CVE-2026-35597 1 Vikunja 1 Vikunja 2026-10-26 N/A 5.9 MEDIUM
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the TOTP failed-attempt lockout mechanism is non-functional due to a database transaction handling bug. When a TOTP validation fails, the login handler in pkg/routes/api/v1/login.go calls HandleFailedTOTPAuth and then unconditionally rolls back. HandleFailedTOTPAuth in pkg/user/totp.go uses an in-memory counter (key-value store) to track failed attempts. When the counter reaches 10, it calls user.SetStatus(s, StatusAccountLocked) on the same database session s. Because the login handler always rolls back after a TOTP failure, the StatusAccountLocked write is undone. The in-memory counter correctly increments past 10, so the lockout code executes on every subsequent attempt, but the database write is rolled back every time. This allows unlimited brute-force attempts against TOTP codes. This vulnerability is fixed in 2.3.0.
CVE-2026-40485 2026-10-26 N/A 5.3 MEDIUM
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the public API login endpoint (/api/public/user/login) returns distinguishable HTTP response codes based on whether a username exists: 404 for non-existent users and 401 for valid users with incorrect passwords. An unauthenticated attacker can exploit this difference to enumerate valid usernames, with no rate limiting or account lockout to impede the process. This issue has been fixed in version 7.2.0.
CVE-2026-41213 1 Node-oauth 1 Node-oauth\/oauth2-server 2026-10-26 N/A 5.9 MEDIUM
@node-oauth/oauth2-server is a module for implementing an OAuth2 server in Node.js. The token exchange path accepts RFC7636-invalid code_verifier values (including one-character strings) for S256 PKCE flows. Because short/weak verifiers are accepted and failed verifier attempts do not consume the authorization code, an attacker who intercepts an authorization code can brute-force code_verifier guesses online until token issuance succeeds.
CVE-2026-6947 2026-10-26 N/A 7.5 HIGH
DWM-222W USB Wi-Fi Adapter developed by D-Link has a Brute-Force Protection Bypass vulnerability, allowing unauthenticated adjacent network attackers to bypass login attempt limits to perform brute-force attacks to gain control over the device.
CVE-2026-33763 1 Wwbn 1 Avideo 2026-10-26 N/A 5.3 MEDIUM
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `get_api_video_password_is_correct` API endpoint allows any unauthenticated user to verify whether a given password is correct for any password-protected video. The endpoint returns a boolean `passwordIsCorrect` field with no rate limiting, CAPTCHA, or authentication requirement, enabling efficient offline-speed brute-force attacks against video passwords. Commit 01a0614fedcdaee47832c0d913a0fb86d8c28135 contains a patch.
CVE-2026-2402 1 Schneider-electric 1 Powerchute Serial Shutdown 2026-10-26 N/A 5.3 MEDIUM
CWE-307 Improper Restriction of Excessive Authentication Attempts vulnerability exists that would allow an attacker to gain access to the user account by performing an arbitrary number of authentication attempts with different credentials on a sequence of requests to multiple endpoints.
CVE-2026-41037 1 Qntmnet 2 Qn-i-470, Qn-i-470 Firmware 2026-10-26 N/A 8.8 HIGH
This vulnerability exists in Quantum Networks router due to missing rate limiting and CAPTCHA protection for failed login attempts in the web-based management interface. An attacker on the same network could exploit this vulnerability by performing brute force attacks against administrative credentials, leading to unauthorized access with root privileges on the targeted device.
