Vikunja before 2.7.1 Password Brute-Force via TOTP Disable Endpoint

Vikunja before 2.7.1 contains an improper restriction of excessive authentication attempts vulnerability that allows session holders to brute-force account passwords via unthrottled re-authentication endpoints. Attackers with a stolen session can guess the password via /user/settings/totp/disable without lockout, then disable TOTP without a code for persistent account takeover.

HCL AION is affected by multiple security vulnerabilities.

HCL AION is affected by a vulnerability where the account lockout mechanism did not sufficiently restrict repeated failed login attempts, allowing an attacker to make a large number of password guesses against a user account. This may increase the risk of account compromise through brute-force attacks, potentially resulting in unintended behavior or security impact under certain conditions.

BCK Auto-confirm Bank Transfer <= 2.0.1 - Unauthenticated WooCommerce Order Payment Confirmation

The Thanh Toán Quét Mã QR Code Tự Động WordPress plugin through 2.0.1 does not properly verify the authenticity of incoming bank-transfer payment notifications on a default installation, allowing unauthenticated attackers to mark arbitrary WooCommerce orders as paid.

EASY-JS-WPAPI <= 2.0 - Unauthenticated Administrator Password Disclosure and Authentication Bypass

The EASY-JS-WPAPI Client HANDLE for the WordPress REST-API WordPress plugin through 2.0 does not prevent the administrator credentials it stores from being disclosed to unauthenticated users and does not correctly verify authentication, allowing unauthenticated attackers to obtain administrator credentials and gain full administrator access to the site.

Bruteforce Protection Bypass in WidzialniCMS

WidzialniCMS is vulnerable to Bruteforce Protection Bypass in the login functionality. The cookie-based lockout can be bypassed by omitting the login_count and login_timeout cookies, allowing an unauthenticated attacker to perform an unlimited number of login attempts. This issue has been fixed in version 2.5.

BlueprintUE Self-Hosted Edition 4.2.0 before 4.3.4 Login Rate Limit Bypass

BlueprintUE Self-Hosted Edition 4.2.0 before 4.3.4 contains a login rate limit bypass vulnerability in LoginMiddleware.php that keys failed-login counters on case-sensitive usernames. Unauthenticated attackers can vary username casing against case-insensitive MySQL lookups to get extra attempts and brute-force passwords past the per-account lockout.

Databasus 3.7.0 through 3.61.0 Account Takeover via Password Reset Brute-Force

Databasus 3.7.0 through 3.61.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to brute-force password reset codes via POST /api/v1/users/reset-password. Attackers can request a six-digit code for a known email, then guess it without rate limiting, lockout, or invalidation to take over accounts, including administrators.

pgAdmin 4: The failed login limit can be bypassed, and Flask-Security's own views skip pgAdmin's login and password checks

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.

SonicOS SSLVPN improper restriction of excessive MFA attempts vulnerability allows an authenticated attacker to use excessive MFA codes.

Chartbrew: Unauthenticated Brute Force of Password-Protected Dashboards Due to Missing Rate Limit and Plaintext Password Storage

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.3, public dashboard passwords were stored in plaintext, accepted through a URL query parameter, and checked without effective attempt throttling. The vulnerable surface is public password-protected dashboard storage and validation routes. An unauthenticated attacker targets a public password-protected dashboard and repeatedly submits candidate passwords or obtains password-bearing server or proxy logs. Unlimited online guesses enable brute force, while cleartext storage and URL transport expose the secret in application storage and server or proxy access logs. The target must be a public dashboard with password protection enabled. Even failed attempts reveal chart count and configuration without the password; a recovered password grants access to the protected dashboard and its chart data. This vulnerability is fixed in 5.2.3.

Hisense VIDAA Smart TV MQTT Broker Authentication Bypass

Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an authentication bypass vulnerability in its remote-control MQTT broker on TCP port 36669, which accepts publicly documented default credentials and an ineffective 4-digit pairing PIN with no rate limiting or lockout, allowing a brute force of the entire code space in about five seconds, while some actions require no pairing at all. A LAN-adjacent attacker can exploit this to inject key events, change volume, switch input sources, enumerate inputs, launch arbitrary installed applications, and monitor pairing activity, posing a significant risk in hotel deployments where untrusted LAN access is common.

Unauthenticated Improper Restriction of Excessive Authentication Attempts in the API of HPE Networking Fabric Composer

An improper restriction of excessive authentication attempts vulnerability in the API of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to conduct brute-force attacks against user accounts if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to gain administrative access to the affected system.

Password Brute Force via Password History Validation in Multiple WSO2 Products Allows User Account Discovery

The RemoteUserStoreManagerService does not sufficiently validate password change attempts when the password history validation feature is enabled. This oversight allows an attacker to repeatedly attempt password guesses for a user account without being adequately restricted. Exploiting this vulnerability enables an attacker to discover a user's password through brute force, leading to account impersonation. The success rate of such an attack is influenced by the complexity of the targeted user's password, with simpler passwords increasing the likelihood of compromise.

Applying a patch is advised to resolve this issue.

Kernel: ksmbd brute force delay bypass via asynchronous requests

A vulnerability has been identified in the Linux kernel's ksmbd component (kernel SMB/CIFS server). A security control designed to prevent dictionary attacks, which introduces a 5-second delay during session setup, can be bypassed through the use of asynchronous requests. This bypass negates the intended anti-brute-force protection, potentially allowing attackers to conduct dictionary attacks more efficiently against user credentials or other authentication mechanisms.

OpenEMR 7.0.1 before 8.4.0 OneTimeAuth Token Replay and PIN Brute Force

OpenEMR from 7.0.1 before 8.4.0 contains a flaw in src/Common/Auth/OneTimeAuth.php that ignores the enforce_onetime_use and max_access_count flags, never revokes consumed service_auth tokens, and checks login_pin without rate limiting or strict comparison. Attackers holding a captured token can replay it or brute-force the PIN to open patient-portal sessions exposing PHI.

Shield - Moderately critical - Access bypass - SA-CONTRIB-2026-248

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.

Keycloak-services: keycloak-services: device authorization grant issues tokens to brute-force-locked accounts

A flaw was found in the Device Authorization Grant flow of Keycloak, an identity and access management solution. The issue occurs because the token redemption process fails to check if a user account is currently locked due to brute-force protection. If an attacker has an active session for a locked account, they can complete the device login process and receive new security tokens. This allows the attacker to maintain access to the account even when it should be temporarily disabled to prevent unauthorized entry.
