CVE-2026-105638 Critical · 9.1 CWE-307 Oct 5, 2026

Plane magic-code login: missing limit on failed attempts (CVE-2026-105638)

Plane is an open-source project management tool. Prior to 1.4.0, Plane's magic-code email login uses a six-digit numeric OTP with approximately 20 bits of entropy. The verifier has no per-code failed-attempt counter, and an incorrect code does not increment a counter, invalidate the Redis entry, or lock the email address. The verifier extends django.views.View rather than DRF's APIView, so the configured AnonRateThrottle limit does not apply. The middleware stack also contains no Django-level rate limiter such as django-ratelimit, django-axes, or an IP-throttling middleware. This vulnerability is fixed in 1.4.0.

CVE-2026-102825 Low · 3.7 CWE-307 Sep 29, 2026

Russh: Configured server auth-attempt cap is not enforced in the USERAUTH_REQUEST runtime path

Russh is a Rust SSH client and server library. Prior to 0.62.6, the USERAUTH_REQUEST path reached from server::run_stream in russh/src/server/encrypted.rs increments self.common.auth_attempts but never compares it with server::Config.max_auth_attempts. An unauthenticated remote client can continue submitting authentication requests on one connection beyond the configured cap, bypassing the deployment's attempt-limiting policy and increasing online guessing opportunity and backend authentication workload. This issue is fixed in version 0.62.6.

CVE-2026-102334 High · 7.4 CWE-307 Sep 28, 2026

GLPI: Missing Rate Limiting on Login and TOTP Verification — Account Takeover via Brute Force

GLPI is a free asset and IT management software package. From 11.0.0 until 11.0.8, the time-based one-time password verification endpoint does not limit failed submissions per user. An attacker who has obtained a user's primary authentication credentials can repeatedly submit TOTP values against the MFA verification flow, making brute-force compromise of the second factor and subsequent account takeover possible. This issue is fixed in version 11.0.8.

CVE-2026-37603 Medium · 6.5 CWE-307 Sep 22, 2026

Improper Restriction of Excessive Authentication Attempts in the administration login of…

Improper Restriction of Excessive Authentication Attempts in the administration login of pH7Software pH7Builder (pH7 Social Dating CMS) through 19.2.0. The CAPTCHA escalation flag is stored in the PHP session as captcha_admin_enabled and the CAPTCHA form element is only built when that flag is present, so a remote unauthenticated attacker who obtains a new session before each login attempt is never presented with the challenge.

CVE-2026-85734 Critical · 9.1 CWE-307 Sep 22, 2026

LightRAG: No Rate Limiting on /login Endpoint Allows Brute-Force Attacks

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, the POST /login endpoint in lightrag/api/lightrag_server.py does not impose a rate limit, account lockout, delay, or counter for failed authentication attempts. A network attacker can submit password guesses at full request speed until a valid account password is found. Successful credential recovery grants authenticated access to documents, the knowledge graph, and administrative operations. This issue is fixed in version 1.5.5.

CVE-2026-56682 Medium · 5.3 CWE-307 Sep 22, 2026

9Router: Login Brute-Force Lockout Bypass via Spoofable X-9r-Real-Ip Header

9Router is an AI router & token saver. Prior to 0.5.6, 9Router deployments that allow requests to reach Next.js without the sanitizing custom-server.js wrapper use the client-supplied X-9r-Real-Ip value as the bucket key in getClientIp, checkLock, and recordFail in src/lib/auth/loginLimiter.js for POST /api/auth/login. A remote unauthenticated attacker can rotate the header on every password guess so each request uses a new failed-attempt bucket and the five-attempt progressive lockout never returns HTTP 429. This permits unthrottled password guessing against the dashboard login and can lead to an administrative session if the password is recovered. This issue is fixed in version 0.5.6.

CVE-2026-46649 Critical · 9.1 CWE-307 Sep 21, 2026

Joplin: SSO Auth Code Login Missing Rate Limiting — 9-Digit Numeric Code Brute-Forceable via Unprotected Endpoint

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Server's GET /api/login_with_code/:id endpoint accepts a nine-digit SSO authentication code with a ten-minute lifetime without applying limiterLoginBruteForce. An unauthenticated attacker who targets a user during an active SSO login can make unlimited guesses, and a correct code returns a full session token that permits access to and modification of the user's notes, notebooks, and account settings. This issue is fixed in version 3.7.2.

CVE-2026-58271 Medium · 6.8 CWE-307 Sep 21, 2026

@sync-in/server vulnerable to TOTP Brute-Force via `POST /api/app/sync/register`

Sync-in Server is an open-source platform for file storage, sharing, collaboration, and syncing. Prior to version 2.4.0, `POST /api/app/sync/register` accepts credentials and a TOTP code to register a desktop sync client. On a failed TOTP, `SyncClientsManager.register()` calls `updateAccesses(user, ip, false)`, which hits a freeze branch that writes `passwordAttempts` back unchanged. The counter never reaches `USER_MAX_PASSWORD_ATTEMPTS` (10) and the lockout gate never fires. A successful guess returns a `{clientId, clientToken}` pair. The token can be exchanged via `POST /api/app/sync/auth/cookie` for a full JWT. While the code is valid, the attacker can also call `POST /api/auth/2fa/disable` to permanently remove MFA. Version 2.4.0 patches the issue.

CVE-2026-77561 Medium · 5.3 CWE-307 Sep 21, 2026

Tinyauth: Unauthenticated login attempts can trigger global login lockdown denial of service

Tinyauth is an authentication and authorization server. Prior to 5.1.0, an unauthenticated remote attacker can send POST /api/user/login requests with 257 distinct nonexistent usernames to fill MaxLoginAttemptRecords and activate a global login lockdown. internal/controller/user_controller.go loginHandler passes each attacker-controlled identifier to internal/service/auth_service.go RecordLoginAttempt, which invokes lockdownMode after the map reaches its cap. IsAccountLocked checks that global state before validating unrelated accounts, causing valid users to receive HTTP 429 until auth.loginTimeout expires, approximately 300 seconds by default. The attack can be repeated, but existing authenticated sessions are not invalidated. This issue is fixed in version 5.1.0.

CVE-2026-93650 Low · 3.7 CWE-307 Sep 18, 2026

Payara Server is vulnerable to brute-force login attacks due to the absence of a limit on failed login attempts

By default, Payara Server does not limit the number of failed login attempts, which can leave it vulnerable to brute force login attacks. To mitigate this, Payara Server includes built-in automatic attack protection. For configuration details, see https://docs.azul.com/payara/technical-documentation/payara-server-documentation/security-guide/administering-system-security.html .

CVE-2026-55795 Medium · 6.9 CWE-307 Sep 14, 2026

Craft Commerce: Coupon Code Brute-Force via Rate Limit Bypass

Craft Commerce is an ecommerce platform for Craft CMS. From 4.0.0 until 4.11.2 and 5.6.5, CartController in src/controllers/CartController.php activates its RateLimiter only when the number POST or GET parameter is supplied. An unauthenticated attacker can submit couponCode values to actionUpdateCart for the session-based cart while omitting number, preventing creation of the IP rate-limit identity and allowing unlimited automated coupon-code guessing and enumeration. This issue is fixed in versions 4.11.2 and 5.6.5.

CVE-2026-89174 High · 7.5 CWE-307 Sep 11, 2026

CVE-2026-88770 Medium · 6.5 CWE-307 Sep 10, 2026

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.
